Penguin Studio 0.6.3 — Linux development preview

Download the package matching your system from Assets below. All package builds
and their automated checks passed before publication. Full live-provider,
hardware and cross-desktop testing is still incomplete; see docs/VERIFICATION.md.

Target	Download
Ubuntu 24.04 (amd64)	penguin-studio_0.6.3-1+ubuntu24.04_amd64.deb
Ubuntu 26.04 / 26.04.1 (amd64)	penguin-studio_0.6.3-1+ubuntu26.04_amd64.deb
Fedora 44 (x86_64)	penguin-studio-0.6.3-1.x86_64.rpm
AppImage (x86_64, glibc 2.39+)	penguin-studio-0.6.3-x86_64.AppImage
Arch Linux / AUR recipe (x86_64)	penguin-studio-0.6.3-aur.tar.gz
Flatpak (x86_64)	penguin-studio-0.6.3-x86_64.flatpak
Snap core24 (amd64)	penguin-studio_0.6.3_amd64.snap
Optional RX 9070 camera GPU runtime (Ubuntu 26.04)	penguin-studio-camera-amd-gfx1201_0.6.3-1+ubuntu26.04_amd64.deb

Ubuntu DEBs are release-specific; do not install the 24.04 package on 26.04.
The RPM targets Fedora 44. Flatpak requires the Freedesktop 25.08 runtime
from Flathub. Snap requires snapd and local installation with --dangerous;
it is a development build, not a Snap Store publication.
AppImage targets x86_64 hosts with glibc 2.39 or newer. Make it executable and
launch it; --appimage-extract-and-run avoids a FUSE dependency. The AUR archive
contains a checksum-pinned penguin-studio-bin recipe, not a claim of publication
on aur.archlinux.org. Extract it, review PKGBUILD, then run makepkg -si on Arch.
AppImage and Arch installations currently use manual/package-manager updates;
the in-app updater offers release links instead of replacing those installations.

Verify downloaded files with sha256sum --check SHA256SUMS after downloading

Security and reliability maintenance

Penguin Studio 0.6.3 hardens media and RTMP packet parsing, bounds nested AMF decoding, and updates the embedded browser to OBS Browser 2.27.4 with CEF 7871. It includes upstream corrections for audio/video task deadlocks, ALSA device shutdown and duplicate PipeWire captures in Studio Mode. Author and license notices are preserved.

Camera GPU processing

Automatic/GPU/CPU preferences keep camera effects available with automatic CPU
fallback. GPU initialization runs in an isolated helper so slow compilation or a
driver failure cannot block initialization of the main window. Primary RVM runs
on the GPU; hand preservation remains on CPU after direct mask comparisons found
incorrect contours from the current AMD hand-model graph. The confirmed RX 9070
XT Facecam movement test under Wayland completed 1,504 recording frames without
reported rendering/encoding losses, with a fully readable file and clean exit.
This is measured evidence for that configuration, not a zero-loss guarantee.

An optional Ubuntu 26.04 gfx1201 runtime add-on accompanies the regular downloads.
It does not replace system drivers. Other packages retain CPU fallback; see the
package guide for scope and installation.

Validation

All eight Linux download artifacts passed candidate build 40201246032. The Ubuntu 26.04 package passed native Wayland camera/Inspector checks, 211 workspace checks, nine shutdown scenarios, local horizontal/vertical RTMP tests, saved Twitch/YouTube sessions and category searches, and the GitHub update check. The package's 1,498-frame GPU reference recording kept GPU processing active, reported no rendering/encoding losses, decoded fully and exited cleanly. A separate 1,501-frame CPU reference recording also decoded without reported frame-loss events. Current English previews use this real package with synthetic local media.

The short workspace smoke recording reported two render-lag frames; zero-loss performance is not universal. A sporadic Qt Wayland text-input focus warning was observed when opening the updater, including a restart test. Delayed opening and the dedicated focus/close scenario passed, but this warning is not considered fully resolved; release queries and normal shutdown still succeeded. Full provider broadcasts and all hardware/distribution combinations remain outside this test scope. Private webcam recordings and account data are not published. No claim of complete security or perfect segmentation is made.

Linux downloads

Choose the DEB matching Ubuntu 24.04 or 26.04, Fedora RPM, Flatpak, Snap, AppImage or Arch recipe. Verify downloads against SHA256SUMS. Ubuntu 26.04.1 uses the Ubuntu 26.04 DEB. The Arch recipe is downloadable; a public AUR listing is not provided. Penguin Studio remains a development preview.

Installed Ubuntu verification — 2026-10-25

The published Ubuntu 26.04 main package and optional gfx1201 runtime were verified against SHA256SUMS and installed on Ubuntu 26.04.1. Installed-file verification passed. A native Wayland reference recording with Automatic processing selected the RX 9070 XT, produced 1,513 frames without reported render/encoding losses, decoded fully and exited normally with no warning/error diagnostics or reported memory leaks. An earlier attempt correctly fell back to CPU when the temporary filesystem quota prevented GPU compilation; moving private test artifacts to SSD resolved that environmental failure. The known sporadic updater-opening Qt focus warning remains documented above.
