Your view needs redrawing, and the frameworks are breaking down the dirty region into non-overlapping component rects that are drawn separately. It just happens that this decomposition process leaves a tiny rect to be drawn separately. As to why it decomposes this way, my guess would be that your view has subviews (and/or controls) which are misaligned by a single pixel, changing what would otherwise be a nice rectangular dirty region into something slightly more complex. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
