Hello, I have a custom layer-hosting NSView with a nested layer hierarchy. The view updates one if its layers in response to mouse-dragging to highlight a selection of things it displays.
Sometimes - randomly and very infrequently - I get a very flash of complete blackness or whiteness in the same screen area the layer it updated. I would guess it lasts only one screen refresh cycle, so the flash is really very brief. Has anyone seen something similar? I can't recreate it, I don't what causes it, I only know it has something to do with my drawing the layer or updating the layer and it only happens when I drag the mouse and update the selection layer. My layers are all delegate-drawn, I'm not using transforms or animations, I don't use filters or background filters on any of the layers. Content animation is turned off as well (via -actionForLayer:forKey:). I'm at a complete loss here. I would appreciate any input/wild speculation as to what could/may cause an effect like this. I'd be happy to supply more/any information and a compiled test application, though - given my inability to reliably recreate the issue - you could never see it.
