Panning the Sound tab drew the whole wave anew on every move, one filled rectangle per pixel column, and gave the ruler's labels new texts whenever a tick left the area. At 2560 px across that took the tab down to 16 fps. - The wave is drawn half the area's width past either side of it. A pan within that moves the drawing. Zoom, height, size or a pan past the margin draw it anew. - The bars of the wave share one fill instead of one fill each. - A ruler label keeps the second it already shows. Before, a pan shifted every label by one and each had to be rendered anew. - A clip's name is given its style only when the style changes. - The rule for what a drawing covers is pure in `waveView.ts` (`shownSeconds`, `drawnSeconds`, `coversShown`). Measured with a copy of the user's project, "Take 1" with 4 clips, 240 pan moves with the middle button, headless on stein2: - 2560x1440: main thread 712 -> 373 ms/s, texts rendered 694 -> 65 - 1280x800: main thread 429 -> 225 ms/s What is left in the profile is Pixi's render pass and the pointer events, which hovering pays as well. Tests: - Unit wave-view: 12 green (1 new), counter-probe red - e2e 34 (stein2, melektaus-atx was down): ALL PASSED, 92 checks (1 new). Counter-probe with the labels given out by position: red, 7 labels set anew instead of 1. - Gate (stein2): 272 files, 4210 tests green Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
