Capturo 0.31.0

Windows x64 Setup and Portable executables, plus an unsupported Apple Silicon macOS preview.

Added

Panoramic Scrolling (Windows and macOS). A normal screenshot selection becomes one live, direction-free long capture. Every accepted frame infers up, down, left, or right on its own, so a single session can change axes or retrace a route without a direction prompt. A compact bar outside the captured pixels shows a miniature of everything captured so far, a thin cyan outline marks the viewport being followed, and Finish opens the stitched PNG in Full Tab.

Your mouse pointer stays visible throughout and keeps working normally; Capturo tracks its footprint and fills those pixels from a later clean observation rather than baking a cursor into the image.

Unsafe frames fail closed: unchanged, ambiguous, periodic, or too-fast movement is rejected and Capturo asks you to pause or retrace instead of inventing a seam. Output is bounded to 30,000 pixels per axis and 120 million pixels total, and keeps transparency because a two-dimensional route can leave uncaptured space inside its bounding box.

Full Tab image zoom and pan. Visible zoom-out, percentage/Fit, and zoom-in controls alongside Ctrl/Cmd+-, Ctrl/Cmd+0, and Ctrl/Cmd++. Ctrl/Cmd-wheel zooms around the pointer; an ordinary wheel pans a magnified image.

Fixed

HDR captures can no longer be silently over-exposed. The SDR white level that the whole frame is divided by comes from a Windows query that can fail transiently. Capturo used to answer one failure with a compiled-in 200 nit guess, which lifts every pixel and clips the highlights on a display whose real level is higher — the same appearance as the HDR handling having stopped working. The query is now retried, an implausible answer is rejected, and the level falls back to the last one actually measured for that display before it ever reaches the guess.

A capture the native helper cannot serve still falls back to the 8-bit path that cannot tone map HDR, but that fallback, and any HDR frame whose white level was not measured, are now reported instead of passing quietly. CAPTURO_TIMING=1 names the pixel format, HDR state, white level and its source per display.

Notes

Panoramic Scrolling runs on macOS in this release as well. It uses the same live display-media stream and out-of-crop control bar that GIF recording already uses there, and the stitching, masking, and bounds logic is identical to Windows. macOS places the control bar inside the work area rather than over the menu bar or the Dock, because AppKit would otherwise slide that capturable chrome back into the recorded viewport; a region that leaves no room outside it declines to start rather than recording its own bar. The macOS path has not yet been walked through the full hands-on matrix, so treat it as less proven than the Windows one.

Windows binaries are not Authenticode-signed, so Windows will show an unknown-publisher warning. Choose More info, then Run anyway if you trust the checksum published alongside them.

Why this is 0.31.0 and not 0.30.0

0.30.0 was tagged and briefly published, then withdrawn. The macOS Panoramic Scrolling work landed
after that tag was cut, so the release would have shipped a disk image that no commit produced.
Moving a published tag to conceal that is worse than not using the version, so 0.30.0 and its tag
were deleted and this work ships here instead. The never-published 0.24.0 contents ship here too.
Neither the v0.24.0 nor the v0.30.0 tag exists.

Windows downloads

• Capturo-Setup-0.31.0-x64.exe — interactive x64 installer; lets you choose the destination.
• Capturo-Portable-0.31.0-x64.exe — single-file x64 executable that runs without installing.

Both are supported Windows builds. Neither is Authenticode-signed, so SmartScreen will warn on
first run; check the executable against the checksum below before running it.

macOS Apple Silicon preview

• Capturo-0.31.0-arm64.dmg — Apple Silicon disk image.
• Capturo-0.31.0-arm64-mac.zip — Apple Silicon application archive.

The macOS packages are an unsupported preview. They are ad-hoc signed and unnotarized because
Capturo does not yet have an Apple Developer ID certificate. Gatekeeper therefore requires manual
intervention after download — it reports "Capturo is damaged and can't be opened", which is its
response to an un-notarized download rather than a corrupted file — and macOS ties the Screen
Recording grant to the build's own code hash, so the permission has to be granted again after this
upgrade.

HDR-correct capture remains Windows-only; macOS falls back to Electron's desktopCapturer.

Verification

• Type checking, all 262 automated tests, the production build, and macOS arm64 packaging passed.
• The DMG passed hdiutil verify and the ZIP passed a complete unzip -t integrity check.
• The macOS bundle signature verifies under codesign --verify --deep --strict, reporting
  Identifier=com.capturo.app and Sealed Resources version=2, and the universal text-recognition
  helper is present at Contents/Resources/ocr/capturo-ocr (x86_64 arm64).
• The macOS preview has not been walked through the full hands-on matrix for this version.
• The Windows x64 artifacts were packaged from this release's source on Windows. The native
  capture helper was rebuilt first and its --self-test passed; type checking, all 262 tests, and
  the production build passed before packaging. The withdrawn 0.30.0 executables predate the macOS
  change and are not reused here.
• Both Windows executables report NotSigned under Get-AuthenticodeSignature. No Authenticode
  certificate was available for this release, so the unknown-publisher warning above is expected.
• The Windows artifacts have not been walked through the full hands-on acceptance matrix for this
  version; the installed and portable launches were not re-tested by hand.

Packaging embeds build timestamps, so it is not byte-reproducible; a differing digest from your own build is not evidence of a source difference.

Capturo 0.22.3

Added

• Open in full tab moves a selected screenshot into a normal resizable, minimizable editor
  window while preserving the current annotations and editing tools.
• Color Picker wheel magnification provides five discrete levels: 8×, 12×, 15×, 22×, and
  40×. The tighter levels progressively slow selector travel for precise pixel selection, and
  arrow keys remain available for exact single-pixel nudges.

Fixed

• Color Picker now opens and samples correctly on macOS. Picker startup no longer relies on an
  Electron screen-conversion API that is declared but absent in the macOS runtime; display image
  dimensions now use the platform-neutral display size and scale factor.
• Color Picker movement stays aligned with the physical pointer. Absolute screen-space deltas,
  synchronized native-window recentering, and bounded owned-selector coordinates prevent the
  magnifier from jumping past the cursor, reversing, oscillating, or disappearing during fast
  movement and abrupt direction changes.
• Magnifier trails and stale frames are eliminated. The aperture and color caption are painted
  together in one frame-synchronized canvas, with pointer input coalesced to one visual update per
  display frame.
• The Color Picker hex readout is sharp on scaled displays. Device-pixel backing stores,
  pixel-aligned placement, and a clearer Segoe UI caption remove the former low-resolution blur.
• Fast pointer movement no longer exposes the Windows arrow cursor during a live picker
  session, including while the protected compact window is catching up.
• Maximum zoom remains controllable during very fast mouse movement through zoom-specific
  movement factors and speed ceilings.
• Live samples cannot cross monitor ownership. Delayed grids are accepted only for the current
  display, point, and zoom size.
• Color Picker no longer blurs, greys, or blacks out browser video on Windows. It uses a compact
  protected window and live native pixel grids rather than a monitor-sized transparent Chromium
  surface.
• Open in full tab no longer leaves an invisible editor blocking retries. Capturo waits for the
  detached editor to decode and visibly acknowledge its checkpoint, and clears failed or timed-out
  windows.
• HDR screenshots retain hue and chroma in very bright and dark scenes. Out-of-range RGB values
  are tone-mapped with one shared scale instead of independent channel curves.

Changed

• Color Picker is live and no longer freezes or tints the desktop. Screenshot and GIF region
  selection retain their frozen-desktop workflow.
• Shift no longer changes Color Picker movement. Precision is controlled exclusively by wheel
  zoom or exact arrow-key nudges; there is no temporary modifier-driven focus mode.
• Highlighter colors are substantially brighter while retaining translucent marker blending
  and readable content underneath.
• The Color Picker opens directly without an instruction popup or zoom/focus badge.
• Capture, GIF, and Color Picker shortcuts accept any Electron-supported non-modifier key by itself
  or in a combination, including bare Print Screen when Windows allows its registration.

Windows downloads

• Capturo-Setup-0.22.3-x64.exe — interactive installer with destination selection.
• Capturo-Portable-0.22.3-x64.exe — portable build, no installation required.

Windows packages are currently unsigned and may show an unknown-publisher or SmartScreen warning.

macOS Apple Silicon preview

• Capturo-0.22.3-arm64.dmg — Apple Silicon disk image.
• Capturo-0.22.3-arm64-mac.zip — Apple Silicon application archive.

The macOS packages are an unsupported preview. They are ad-hoc signed and unnotarized because
Capturo does not yet have an Apple Developer ID certificate. Gatekeeper therefore requires manual
intervention after download, and Screen Recording permission may need to be granted again after an
upgrade.

Verification

• Type checking, all 210 automated tests, the production build, and Windows x64 packaging passed.
• Regression coverage verifies macOS display-pixel sizing, frame coalescing, full-canvas clearing,
  zoom-scaled motion, recentering, display ownership, detached-editor readiness, and the absence of
  Shift-driven picker precision.
• The packaged macOS arm64 build was exercised locally through picker rendering, exact selection,
  clipboard copy, the result window, the Command+Shift+9 shortcut, and Esc cancellation.
• The DMG passed hdiutil verify, and the ZIP passed a complete unzip -t integrity check.
• Both Windows executables report product and file version 0.22.3.

Capturo 0.22.0

Capturo 0.22.0

Windows and macOS artifacts are both attached. The Windows pair was packaged separately on a
Windows 11 x64 host, since Windows packaging cannot run from a macOS host. Windows users can take
this release; the macOS build carries the Gatekeeper caveat described below.

Copy text now works on macOS

Text extraction was Windows-only, because recognition ran through Windows.Media.Ocr. macOS now
has its own local recognizer: Apple's Vision framework, in a small helper alongside the app.

It keeps every guarantee the Windows path has. Recognition happens on your machine — no image is
uploaded, no model is downloaded, no temporary screenshot is written, and no network connection is
opened. It needs no permission of its own, so Copy text raises nothing new. And unlike Windows
there is no language pack to install: 30 recognition languages ship with macOS, so the "install
a language pack" message can never appear on a Mac.

As on Windows, Copy text reads the final selection — crop, annotations, and privacy effects
included — so text you hid behind Blur or Pixelate stays hidden.

Measured on Apple Silicon: a 3024×1964 capture with 40 lines of text was recognized exactly, in
about 1.2 seconds.

New default shortcuts

Action	Was	Now
Screenshot	Ctrl/Cmd+Shift+2	Ctrl/Cmd+Shift+7
GIF	Ctrl/Cmd+Shift+3	Ctrl/Cmd+Shift+8
Color picker	Ctrl/Cmd+Shift+4	Ctrl/Cmd+Shift+9

Shift-Cmd-3 through Shift-Cmd-6 belong to macOS — they are its own screenshot and recording
shortcuts. Capturo's GIF default sat on "screenshot selection to file" and the color picker on
"screenshot and recording options", so on a Mac those two defaults were fighting the system
instead of starting a capture. Nothing in the 7/8/9 range is claimed by macOS or Windows.

Your existing shortcuts are not touched. Whatever is saved in your settings stays bound; only a
fresh install or an explicit Reset picks up the new values. If you are upgrading on a Mac and
your GIF shortcut is still Cmd+Shift+3, press Reset on the GIF tab to escape the collision.

Settings

Every tab now leads with its shortcut. Capture and GIF previously listed theirs last while Color
picker listed it first, so the one control every tab has in common sat in a different place on each.

macOS

Capturo-0.22.0-arm64.dmg and Capturo-0.22.0-arm64-mac.zip are Apple Silicon only. Intel
Macs are not covered by this release.

⚠️ Capturo still has no Apple Developer ID certificate, so this build is ad-hoc signed. Gatekeeper
will refuse to open it after download, typically reporting "Capturo is damaged and can't be
opened" — that is Gatekeeper's response to an un-notarized download, not a corrupted file. macOS
also ties the Screen Recording permission to the exact build, and an ad-hoc signature cannot hold
that grant, so screen capture may not work at all on a machine that downloads this. A signed,
notarized build remains the fix and the blocker for supported macOS releases.

Windows

Built on a Windows 11 x64 host. Capturo-Setup-0.22.0-x64.exe is the installer;
Capturo-Portable-0.22.0-x64.exe needs no install. Copy text and HDR-correct capture continue
to run through the native Windows helper.

If you are upgrading, your existing shortcuts are untouched — the new 7/8/9 defaults apply only to
a fresh install or to Reset in Settings.

Windows binaries are not code-signed. Capturo has no Authenticode certificate, so SmartScreen
shows an unknown-publisher warning on first run. Verify the checksums below before trusting a
download.

Local rebuilds will not reproduce these digests. electron-builder embeds build timestamps, so
packaging is not byte-reproducible; a differing digest is not evidence of a source difference.

Verification

173 automated tests, typecheck, and the production build pass. The packaged build was installed from
the DMG on macOS 26.2 / Apple Silicon and completed the full Copy text path — app, helper, and the
real system clipboard — with the bundle passing codesign --verify --deep --strict.

The Windows build was packaged and checked on Windows 11 x64: both executables report product
version 0.22.0, and the packaged app registers every shortcut it is bound to. Note that an existing
install keeps its saved bindings, so upgrading does not move you onto 7/8/9.

Capturo 0.21.0

Capturo 0.21.0

Highlighter

A highlighter beside the Pen in the toolbar (H) that marks without covering: the stroke
multiplies into the image, so text underneath keeps its contrast and stays readable rather than
being washed towards the highlight colour.

Every annotation color works, Shift or Ctrl locks the stroke straight for running along a
line of text, and it has its own Size range separate from the Pen's — wide enough to cover a line
of text — plus the same smoothing. Finished strokes move, resize and restyle like any annotation.

On a very dark background the effect is deliberately subtle: multiplying a near-black pixel by any
color leaves it near-black. Rectangle and Blur remain for emphasis that does not depend on what is
underneath.

Color picker

Pick a color from anywhere on screen. Color picker in the tray menu — directly below New GIF, or Ctrl/Cmd+Shift+4 — freezes the desktop and replaces your mouse cursor with a magnifier: the surrounding pixels at 17x, the pixel it is reading outlined in the middle of the aperture, and its hex value below.

Picking copies the color straight to your clipboard — no second step for the thing you came to do, in whichever format you set under Settings.

• Hold Shift for pixel-by-pixel. Sampling slows to an eighth speed, so a one-pixel window border or an anti-aliased edge stops being a matter of luck. Release and the magnifier carries on from where you left it rather than jumping back to the cursor.
• Arrow keys nudge exactly one pixel, for when you want to be certain.
• A Color picker tab in Settings with a rebindable shortcut, alongside the existing capture and
  GIF bindings. Automatic copying can be switched off there, and the format it copies set to HEX,
  RGB or HSL.
• Multi-monitor aware. It opens on the pixel your pointer is already over, shows nothing on
  the displays your pointer is not on, and Shift works on whichever monitor you are using.
• Click, Enter, or Space picks. Esc cancels.

The color window then opens on top of that, with the value as HEX, RGB, or HSL, live hue, saturation, lightness and alpha sliders, a row of related colors a click away, and the nearest color name. Everything — the preview, all three readouts, the name, the swatch row — updates while you drag a slider, not on release. You can also type a hex value, copy again in another format with the button or Ctrl/Cmd+C, and use Pick again to return to the screen without losing the color you already have — the window gets out of the way while you pick, so you can sample the pixels it was covering.

The color reported is the pixel of Capturo's own tone-mapped capture, so it matches what a screenshot of that pixel would contain, including on an HDR display. Because the desktop is frozen when the picker opens, a color cannot be picked out of a playing video — reopen the picker to sample the current frame.

Windows

Built on a Windows 11 x64 host. Capturo-Setup-0.21.0-x64.exe is the installer; Capturo-Portable-0.21.0-x64.exe needs no install.

Windows binaries are not code-signed. Capturo has no Authenticode certificate, so SmartScreen shows an unknown-publisher warning on first run. Verify the checksums below before trusting a download.

Copy text and HDR-correct capture remain Windows-only: both run through the native Windows helper.

macOS

Not in this release. Capturo 0.21.0 is Windows x64 only.

macOS work has moved a long way — capture, annotation, save, clipboard, GIF, the menu-bar flow and
the permission flow all work on Apple Silicon — but the macOS build carries changes these Windows
artifacts do not, so shipping it under this version number would mean two binaries called 0.21.0
that behave differently. It follows in the next release instead.

⚠️ Capturo still has no Apple Developer ID certificate, so any macOS build here is ad-hoc signed. macOS will refuse to open it after download with "Capturo is damaged and can't be opened" — that is Gatekeeper's response to an un-notarized download, not a corrupted file. macOS also ties the Screen Recording permission to the exact build, so an ad-hoc signed Capturo asks for it again after every upgrade. A notarized build remains the fix and the blocker for real macOS support.

Capturo 0.20.0

Windows binaries are not code-signed. Capturo has no Authenticode certificate, so SmartScreen shows an unknown-publisher warning on first run. Verify the checksums at the bottom of these notes before trusting a download.

Placing text actually works now

• Clicking away places the text. Typing into a text box and then clicking elsewhere in the
  selection used to lose everything typed. The click reopened an empty box at the new point before
  the old one was committed, so the commit saw an empty value and nothing was drawn.
  Ctrl/Cmd+Enter still commits explicitly, and Esc is now the only way to discard.
• Esc cancels the text, not the screenshot. One press used to discard the text and cancel
  the whole capture, taking every other annotation with it. The first press now discards the text;
  a second cancels the capture, the same way Esc already backs out of the transparency panel.
• The resize corner is easy to grab. It was the browser's own ~15px grip, which demanded
  near-pixel aim. It is now a 24px target straddling the corner, so it can be grabbed from outside
  the box as well as inside, and a resize you drag is no longer undone by the next keystroke.

A clearer toolbar

Save carries its own green accent instead of reading as a secondary control beside the two
filled copy actions, and Cancel carries a red tint that deepens on hover, so the one
destructive button in the row is identifiable before it is clicked.

New logo

Capturo has a new mark, applied everywhere: executable and installer, Settings and GIF preview windows, notifications, the Windows notification area, and the macOS menu bar. Icons now have transparent corners rather than the delivered backdrop, and the macOS menu bar uses a monochrome template that follows the light or dark bar and matches the system glyphs beside it.

macOS is a working preview

Verified on macOS 26.2: a menu-bar click starts a capture, the overlay covers the whole display including the menu bar and Dock, Esc cancels immediately, and region selection, annotation, save, clipboard copy, GIF recording, GIF preview, and GIF copy all work.

Capturo-0.20.0-universal.dmg is a universal binary and runs natively on Apple Silicon and Intel.

⚠️ This macOS build is not notarized

Capturo has no Apple Developer ID certificate yet, so the app is ad-hoc signed. macOS will refuse to open it after download with "Capturo is damaged and can't be opened". That is Gatekeeper's response to an un-notarized download, not a corrupted file. To run it anyway, after dragging Capturo to Applications:

xattr -dr com.apple.quarantine /Applications/Capturo.app

Only do that if you trust the checksum below. A notarized build is the fix and remains the blocker for macOS support.

macOS also ties the Screen Recording permission to the exact build, so an ad-hoc signed Capturo asks for it again after an upgrade.

Copy text and HDR-correct capture are Windows-only: both run through the native Windows helper.

Fixed

• Blur now actually blurs the whole region. It was fed only the pixels inside its own
  rectangle, so the blur read transparency past every edge: the effect faded towards the border
  and the untouched original showed through underneath, and raising Intensity only widened the
  faded band. Regions are now blurred with a margin of the surrounding image.
• Copy text now shows a clipboard holding "Aa" and carries its own violet accent beside image
  Copy's blue, so the two copy actions read as a pair without competing for the same colour.

Also fixed on macOS since 0.18.1

• The overlay could not cover the menu bar or Dock, so a duplicate Dock appeared and the menu bar could not be captured.
• Esc did nothing before a region was dragged, including from the global shortcut.
• Screen Recording was requested repeatedly, and Capturo stacked its own dialog on top of Apple's prompt.
• Copying a finished GIF silently did nothing while reporting success.
• The app declared five unused camera, microphone and Bluetooth permissions inherited from Electron. It now declares only Screen Recording and cannot capture audio.

Windows

Built on a Windows 11 x64 host. Both the installer and the portable executable are attached and
report product version 0.20.0. Copy text and HDR-correct capture remain Windows-only.

Capturo-Setup-0.20.0-x64.exe is the installer; Capturo-Portable-0.20.0-x64.exe needs no
install. The docs/ screenshots still show the previous icon and are best regenerated on Windows.

Capturo 0.18.1

Capturo 0.18.1 for Windows x64

Capturo 0.18.1 refreshes the application branding and streamlines the project documentation.

Highlights

• Introduces the new camera/scissors Capturo logo across the installer, executable, Settings
  window, taskbar, notification area, tray menu, and notifications.
• Every logo size is generated from the same supplied source image without an alternate mark,
  crop, mask, recoloring, or transparency conversion.
• Refreshes the README with a concise overview of Capturo's screenshot, annotation, local OCR,
  transparency, GIF recording, update-checking, privacy, and Windows startup capabilities.
• Removes obsolete local release notes and standardizes the remaining documentation wording.

This release retains all v0.18.0 functionality, including local Windows OCR, GIF preview and
animated clipboard copy, connected-background transparency, Blur and Pixelate intensity,
Open on startup, and optional GitHub release checks.

Platform and signing

• Tested and released for Windows x64 only.
• This release publishes the interactive Windows installer. The portable executable remains a
  local validation artifact.
• The installer is not Authenticode-signed, so Windows may display an unknown-publisher warning.
• macOS remains untested, unsigned, un-notarized, unsupported, and is not published.

Capturo 0.18.0

Capturo 0.18.0 — Windows x64

Capturo 0.18.0 adds local text extraction to the screenshot capture workflow.

Highlights

• Copy text now sits immediately beside regular image Copy in the capture toolbar.
• Press Ctrl+Shift+C or click Copy text to recognize the final rendered selection and place
  plain text on the Windows clipboard.
• OCR follows the visible crop, annotations, Blur/Pixelate effects, and a pending transparency
  preview. Empty or failed recognition leaves the editor open with useful feedback.
• Recognition uses Windows' installed OCR languages locally through Capturo's native helper.
  It needs no cloud service, Capturo account, model download, telemetry, or temporary screenshot.
• The helper rejects oversized input and applies a bounded timeout so OCR cannot leave the
  capture editor permanently busy.

OCR can confuse small, stylized, low-contrast, rotated, or obscured characters. Install the
appropriate Windows OCR language pack and review important copied text.

Capturo 0.17.0 — Windows x64

Capturo 0.17.0 is the first release with built-in stable-release checking. It also rolls the
GIF-preview, startup, and privacy-effect improvements developed since the previous public
v0.15.1 release into one tested Windows build.

Highlights

• Check for updates manually from Settings → Global, or opt in to an automatic check after
  launch and at most once per 24 hours.
• Review an available release through Capturo's fixed official GitHub Releases page. Capturo
  never downloads or installs an update and never embeds a GitHub credential.
• Preview completed GIF recordings before export, then Copy, Save, Open folder, Retake, or
  Discard. Windows GIF Copy preserves animation through a native file clipboard entry.
• Optionally open Capturo at sign-in through Settings → Global.
• Control Blur and Pixelate with independent 1–100% Intensity percentages.
• Keep large or slow GIF recordings bounded with timestamp-correct playback, two-frame encoder
  backpressure, localized palette work, and optional frame-count/progress visibility.

Platform and signing

• Tested and released for Windows x64 only.
• This release publishes the interactive Windows installer. The portable executable remains a
  local validation artifact.
• The installer is not Authenticode-signed, so Windows may display an unknown-publisher warning.
• macOS remains untested, unsigned, un-notarized, unsupported, and is not published.

Capturo 0.15.1

Capturo 0.15.1

Capturo 0.15.1 adds non-destructive connected-background transparency editing and refreshes the application branding with the final supplied transparent Capturo logo.

Highlights

• Remove a connected background by sampling a pixel or entering a hex/RGB color.
• Tune perceptual color tolerance and apply up to 10 px of edge feathering.
• Compare Before, After, or draggable Split previews before applying the edit.
• Undo transparency edits with the normal undo shortcut.
• Copy or Save automatically applies a pending transparency preview and preserves alpha as PNG.
• Use the same Capturo logo across the executable, installer, taskbar, tray, and notifications.
• Prevent Electron's unused spellchecker from creating malformed cache folders beside the source tree.

Capturo 0.14.0

Capturo 0.14.0

Windows x64 is the only tested and supported platform for this release.

Highlights

• GIF playback now follows actual active recording time, including late sampling and pauses.
• A configurable 0-10 second pre-timer (default 3 seconds) gives time to prepare before capture begins.
• Bounded encoder backpressure and changed-pixel palette work substantially reduce memory growth, finalization waits, and file size for typical desktop recordings.
• GIF Settings can hide sampled, skipped, processed, ready, and encoded frame totals while retaining the timer and Finalizing/Saving states.
• Windows recording chrome uses exact bounds, protected DWM styling, perimeter-constrained shade tiling, and deterministic ring stacking to prevent grey edge bands.

Validation

• Built and exercised on Windows 11 x64.
• Typecheck, 58 automated tests, production build, native-helper build, GIF smoke recording, and Win32 recording-window geometry inspection passed.
• A representative 30 fps / 70% quality capture retained its complete 27.78-second timeline and produced a 2.41 MB GIF versus roughly 22 MB before the encoding optimizations. Results depend on screen activity and region size.
