Group workspaces with Overview and status controls with the clock. Keep themed backgrounds and borders around each island, with click-through gaps and configurable side padding defaulting to 4 px.
Capture blur within each panel region and update material and input regions when island bounds change. Cover layout reloads and padding changes with widget and native shell tests.
Queue popup, modal and notification material geometry and opacity until the matching content buffer commits. Remove event-handler opacity writes that could present material state ahead of content, while preserving compositor dismissal ownership.
Add pending-presentation regression coverage and update the nested shell lifecycle check.
Share window geometry across overview, resize snapshots and retained closes. Advance close handoffs and group retained rendering by stacking position.
Drive shell motion from surface frames, reuse settled widget content, and synchronize notification materials with each card's fade. Replace physical config keys with duration and bounce, and update documentation and regression coverage.
Open the four display modes from XF86Display or the external-monitor bar icon. Reuse output reconciliation and confirmation for manual layout changes, and notify the shell when monitor state changes.
Release backdrop locks before render-element queries to prevent blurred popups from freezing the compositor. Cover popup open, update and close with regression tests.
Share translucent card styles between display modes and capture sources, show focus rings during keyboard navigation, and align picker buttons, label sizing and footer spacing with system modals.
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.
