piexel cebd582018 Hand the display server one finished map picture per paint
The map drew every visible tile to the window on its own, hundreds of
scaled images per paint, and since tiles are no longer cached in the
display server each of those was uploaded again on every frame, which
made dragging and zooming lag. The tiles are now put together in memory
once, only when tiles or the view change, and drawn as a single image
like the palette view does.

Model used: Claude Opus 5.5
