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.
The Settings portal reads appearance exclusively from the compositor's
theme control socket and falls back to defaults when no compositor is
reachable, so the contract test could no longer assert appearance from an
on-disk KDL document.
Add a fixtures/theme_owner.py peer that speaks the theme IPC framing and
publishes schema-v2 snapshots, point the test at a private runtime socket,
and clear WAYLAND_DISPLAY and WAYLAND_SOCKET so the backend cannot reach a
host compositor. Assert the initial values, the SettingChanged payload
after a republish, and that ReadAll matches the published snapshot, then
confirm an invalid local document does not disturb portal-owned
appearance.
