Ship texture=no in lowGraphics: every paper approach reintroduces an image blend that WebRender re-rasterises each frame, so no texture is the only fast option (with help from vergir-bot LLM) |
Restore the icon mask and real masked wear on the lowGraphics path, keeping only texture off, to measure whether the masks affect scroll caching (with help from vergir-bot LLM) |
