"Terribly high CPU usage, the MacBook gets really hot" - a fanless MacBook Air on a 144Hz screen. Measured on that machine with headed engines (process CPU plus the per-process GPU time macOS keeps): an idle Aero library cost LibreWolf ~110% CPU and ~230ms/s of GPU, the study feed ~130%, Chromium up to ~57% CPU and ~350ms/s of GPU, Safari ~220-250ms/s of WindowServer GPU. Priced one by one: - the gradient mask on .ice-floats re-rendered the animated layer offscreen on every frame (~75 points of Gecko CPU). The floats now rise through a plain rectangular band clear of the header, the bottom chrome and the rail, and fade in and out inside it, so the clip never cuts a visible one; - the overlay grain forced a backdrop readback per frame for a texture that measured a mean <=0.11/255 difference: removed; - the invisible blob drift made every frame a full-screen redraw: the blobs are painted once; - static glass (answer tiles, feedback panel, chips, inputs, dropzones, lists, segmented controls, Aero hint chips) re-blurred the moving scene every frame: only floating glass blurs now, and Aero's baked chat chrome drops a live blur that never showed under the bake; - the scene also parks while the window has no focus and under any dialog or sheet scrim (.scene-pause); the loading icon is a compositor-run CSS animation instead of a framer-motion main-thread loop. After, focused and animating: LibreWolf library 109% -> 33% CPU, study 134% -> 34%, chat 130% -> 42%; Chromium GPU 2.5-4.4x lower with 7-22 points less CPU; Safari's WindowServer GPU -20-26% in Aero, about half in dark. Unfocused or under a sheet: nothing. bubbles-test sweeps every float through 41 phases against the band and pins the parking and the cost contract; tests/heat-probe.mjs (macOS) repeats the measurement; the suites find Playwright's Chromium on macOS. All 15 suites pass, lint clean, the contrast scan lost a finding. Version 0.6.7, SW v89. Co-authored-by: Cursor <cursoragent@cursor.com>
