Instrument redraw sources, per-output request coalescing, and animation fallback scheduling. Route local visual changes to their affected outputs while preserving deferred grab and gesture updates.
Schedule fallback recovery using each orphaned animation output's refresh interval, suppress it while a normal frame chain exists, and retain requested final frames after scheduling failures. Add mixed-refresh, cursor footprint, frame-chain, and disconnect regressions and document measurement limits.
Share a stable damped oscillator solver across scalar and rectangle animations while preserving retarget and explicit no-crossing presentation policies. Add deterministic traces, scrolling and zoom continuity coverage, and pause-aware advancement.
Measure resize barrier and handoff timing behind resize-metrics, expose the feature through the release installer, and wait for the intended backend in isolated portal tests.
Cancel callback-only timers when a frame is submitted and defer callback delivery until retirement. Cover a delayed timer and missed presentation deadline in the scheduler tests.
Clean up shader argument borrows and shell region decoding to pass Clippy.
Detect wallpaper image formats from their contents so extensionless portal copies render on the desktop and lock screen. Preserve decode limits and cover extensionless files with regression tests.
Remove the Bluetooth icon from the status bar.
Resolve light, dark and automatic appearance centrally and publish live theme snapshots to native surfaces and the appearance portal. Add paired preset families, custom theme imports, accessibility transforms and contrast-safe transitions.
Refine the Settings gallery and Auto controls, move overrides under advanced customization, and share palette-aware switches and circular slider thumbs. Document configuration and include theme licenses and integration coverage.
Add adjustable lock-only inactivity delays, a smooth dimming fade and DRM display sleep without changing output layout. Input, session resume and policy changes wake displays. Pending flips retire before power-off, and protected fallback frames preserve the policy after an early locker crash while unlock ownership checks remain strict.
Reduce the password field and avatar, expose delays in Settings, document the practical swaylock comparison and remove the completed backlog.
Validation: independent review cleared; 255 compositor tests, 7 locker tests and 15 Settings tests pass; affected debug binaries rebuilt. Isolated visual smoke remains blocked by an unlocked nested screenshot timeout, matching the previously established baseline presentation limitation. Real DRM display sleep requires a live session check.
