(In reply to comment #2) > (From update of attachment 91777 [details]) > Why does Windows need this change but not Mac? I thought about that. I haven't tried debugging this sequence of calls on Mac. But I'm assuming that there is some Mac specific code that does a setNeedsDIsplay() later in time. Or it could be that CA automatically dirties the layer when changing size and CACF doesn't. I don't think doing a setNeedsDisplay here will hurt Mac. But I could always rejigger the code a bit so this is only done on Windows.

Comment on attachment 91777 [details] Patch Actually, I think you should only repaint if it got larger, and then only the rects that were revealed.
