Optiq Beta 0.5.0

Features and Improvements

Timeline and measurement

• Measure Mode: measure the time delta between events or any two points on the timeline. Includes a measurement toolbar (edge toggle, freehand drag, reset), click-to-place freehand rulers, draggable ruler lines with grab cursors, viewport-clamped labels, and theme-aware highlighting. Measurement state is per-trace so it no longer leaks between loaded traces.
• Right-click a measurement label on the timeline to copy the start time, end time, or measured duration.
• Queue Utilization: per-queue utilization is computed and surfaced on the timeline, shown as a pill in the track meta area.
• Sample counter track statistics (min, max, average, standard deviation) displayed in track meta data, shown as user selectable pills.
• Top Events view: a new view summarizing the most significant events.
• Recolor events that overlap a time-range selection using the main flame color ramp, and draw the translucent selection fill per-track behind events so highlighted colors stay legible.
• Right-click copy for timeline event names and details (mirrors the hover tooltip fields: name, start, duration, ID), gated on the current selection.

Annotations

• Annotations are now track-bound: a note stays attached to its track and follows it as you scroll, reorder, or rearrange the timeline. The track is saved in the project file (older projects still load).
• Expanded notes are now movable floating windows with inline editing: click the title or body to edit in place. New notes open ready to type and are discarded automatically if left empty; the separate Add/Edit dialogs are gone.
• A time guide line appears while a note is hovered or dragged, showing exactly where it is anchored in time.
• The annotations list now includes a Track column, and annotations hide automatically when their track is hidden.

Tracks and meta area

• Track meta-area cleanup: queue utilization rendered as a pill beside the QUEUE pill; removed redundant scale columns and separators.
• Track meta-area tooltip enriched with track ID, type, node/process IDs, and event/sample counts.
• Right-click the track meta area to copy the track name or track ID.
• Track options moved from the gear button into the right-click context menu.
• Track Details statistics (queue utilization, counter min/max/mean/std-dev).
• Histogram header now shows total track count and a per-type breakdown with compact/elided display and full details in a tooltip.
• Fixed track reorder preview clamping.
• Add support for NIC agent type. (Schema 3.0.1 and higher).

Navigation and inspection

• Call Stack table row navigation and highlighting.
• Flow Data table hover and origin highlights, with an owner-row tint marking the event the flow was opened from.
• Copy menu added to the Call Stack table, with fixed cell right-click hitboxes (correct column under cursor) for both flow and call stack tables.
• Right-click copy (row and cell) added to the Kernel Selection and Track Details tables.
• Icons added to context menus across the view (table rows, timeline events, call stack/flow menus, kernel bar-chart column menu) with aligned icon columns.

Compute profiling

• Added support for the LDS AI point on roofline plots.
• Metric table view scrolling and tab-persistence consistency improvements aligned with the comparison tables.
• Added a usage tooltip to the comparison threshold control explaining how to adjust it.

Welcome page and UI

• Homepage/welcome page redesign, now hasStart, Recent, and Resources tiles and logo
• Application look and feel redesign: refreshed app shell, palette, timeline surfaces, compute panels (unified card-based design), memory-chart flow view, and event details/annotations.
• Status bar area now shows active controller requests (or "Ready"), with height that scales to font size.
• Improved splitter and tab visibility
• Newly opened files now activate their tab automatically.
• Saving a project now adds it to the Recent Files list.

Logging and diagnostics

• New user-facing Log Viewer mirroring the application's log stream into a virtualized, filterable, color-coded table: per-level filtering with counts, substring/regex search with highlighting, pause/auto-scroll, absolute/relative timestamps, copy actions, and "open log file".

Rendering and performance

• Lazy render on idle: event-driven rendering so an idle app sleeps (near-zero CPU/GPU) and wakes instantly on input, while loads, async tasks, animations, and in-flight requests keep rendering continuous.
• Texture management rework: startup logo (and other images) uploaded as GPU textures via the modern ImGui textures API instead of per-frame CPU rasterization.
• Migrated to the modern ImGui font-uploading system.

Platform: macOS

• Bundle the MoltenVK driver and ICD manifest into the macOS .app so Vulkan works without a system SDK install.
• Enable macOS notarization: staged Vulkan runtime, entitlements (roc-optiq.entitlements.plist), codesign identity/entitlements CMake options, and license notices.
• Store macOS settings under ~/Library/Application Support/ROCm-Optiq and logs under ~/Library/Logs/ROCm-Optiq.
• Fixed a Mission Control issue that left the Control key stuck (causing Ctrl+Click to act as right-click); consolidated platform helpers under RocProfVis::Platform.
• Disabled the in-app fullscreen toggle (F11 / View > Fullscreen) on macOS, which doesn't match native window behavior.

Fixes

• Memory leaks:
  -call destructors when a memory pool is freed
  -free leaked (sub) futures in model layer
  -future cleanup in system tests
  -Fix Array/Data object ownership.
• Fixed timeline highlight artifacts.
• Duplicate file open protection: canonicalize trace paths so a .db and a .rpv (or two .rpv files) pointing at the same trace are detected, with a clear popup instead of a confusing toast.
• Fixed reopening a .rpv whose source .db is missing: the missing trace is reported by name and no empty 0-byte database is created.
• Fixed multi-node topology node identification (aligned processor topology IDs across instances/queues), plus additional topology display fixes (null parent lookups, out-of-bounds stream processor lookup).
• Fixed the welcome page sometimes appearing only partially drawn until the user moved the mouse or clicked (idle wait is now bounded).
• Corrected stream track entry counts (accumulate record counts across per-operation build queries); bumped the track-info cache version, forcing a one-time rebuild of affected caches.
• Made the per-track table count inclusive on the trace's upper time bound so it matches the tooltip total (off-by-one fix).
• Don't block the UI thread during backend teardown when closing a tab or the application.
• Fixed annotation scroll interactions so annotation scrollbars no longer drive timeline navigation and note dragging is limited to the header.
• Various redesign polish fixes (event details styling, annotation row alignment, metric table row hover, settings table controls, aggregate clear button).
• Fix flow rendering for .rpd traces.
• Fix Compute chart metric mapping.
• Fixed a memory leak related to flow data.
• Fixed a macOS app packaging issue that could prevent the app bundle from being properly signed (static GLFW no longer staged into the bundle).
