Hello, I hope it's OK to discuss an undocumented class on the list.
You can set the background color of the IKImageFlowView in ImageKit with either -(void)setBackgroundColor: or -(void)_setBackgroundColorRed:green:blue:alpha:. This works fine on most machines, but will inevitably cause a crash on systems with the ATIRadeonX2000GLDriver. I have verified this on a number of machines (>10). A crash log is pasted below - they all look the same. It seems the crash occurs in IKImageFlowCell's drawRect:inRect:fromRect... method. (Using the default black background works fine). I have tried setting the color with: NSColor *color = [NSColor colorWithDeviceRed:0.839f green:0.866f blue:0.898f alpha:1.0f]; [super setBackgroundColor:color]; as well as: [super _setBackgroundColorWithRed:0.839 green:0.866 blue:0.898 alpha:1.0]; Both methods result in a EXC_BAD_ACCESS in the ATIRadeonX2000GLDriver when drawing the image flow cell. I don't know if this is a bug in the driver or in Image Kit, but hope there might be someone on the list with some insights into this who can tell me if it is possible to avoid this crash somehow. Thanks in advance. Process: myApp [379] Path: /Users/User/Downloads/myApp.app/Contents/MacOS/myApp Identifier: com.my.app Version: ???
