Include observed timer dispatch delay in the render budget, capped at one refresh and decayed by elapsed time. Preserve the scheduled presentation target and output-local state. Existing scheduling assertions remain intact; a negative control verifies the new deadline regression.
Pin 8a270232f1bfc416c781273c98a3f52a812a0bba and adapt protocol dispatch, input timestamps, configure state and rendering APIs. Preserve custom lock and toplevel validation, compositor-owned key repeats, and valid layer remapping sequences.
Add native icon-buffer lifecycle regressions for the GoLand and Spotify launch failure.
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.
