* perf(terminal): release hidden WebGL canvases' drawing buffers Chromium keeps a display:none WebGL canvas's drawing buffers alive (on macOS a back buffer plus up to four pooled full-size surfaces). Hidden terminal tabs and retained worktrees therefore held ~80 MB of GPU memory each until they were parked. Collapse the canvas backing store while it has no layout box and keep the context; xterm's device-pixel observer restores the size and redraws synchronously on reveal. 7 terminal tabs, 1920x1050@2x: GPU process 670-760 MB -> 350-408 MB. * perf(terminal): free hidden canvases only after 30s and never for suspended worktrees Reallocating the backing on reveal cost about one frame. Delaying the release keeps rapid switching allocation-free, and worktree-suspended panes keep their backing so worktree switches match main. A MutationObserver re-checks a canvas that xterm resizes while hidden. * fix(terminal): restore released WebGL canvases before the reveal frame paints - Reveal restore reallocates at the current DPR and draws past xterm's paused renderer inside the ResizeObserver callback, so the first painted frame has content; also covers engines without devicePixelContentBoxSize. - DPR repair reports released canvases as 'released' (current) instead of 'deferred', so window-resize recovery stops retrying them. - Veto release for panes of a hidden worktree surface (marked from isWorktreeActive) instead of webglAttachmentDeferred, which a hidden prewarm clears. - Schedule release for canvases attached or regrown while already boxless; a zero-size element gets no initial ResizeObserver entry. - Clear the timer through the canvas's own window. * test(terminal): guard hidden WebGL canvas release and reveal restore * perf(terminal): restore a released WebGL canvas at its exact device size without a full resize Set the backing to the reveal entry's device-pixel size (xterm's own fallback size where that box is unavailable) and draw once, instead of handleResize: xterm's device-pixel observer then finds nothing to resize, which removes a second reallocation and redraw from the reveal. A DPR change while hidden still takes the full resize path. * fix(terminal): paint a revealed released canvas through a held synchronized-output frame A released canvas has no last coherent frame to keep, so when a TUI holds DEC 2026 at reveal, the buffered refresh left it blank for up to xterm's 1s watchdog. Use forceFullViewportPresent, which draws the current buffer once directly; the TUI's sync end still presents its finished frame normally. --------- Co-authored-by: m4air <m4air@Mac.localdomain>
