> There is (or was) a QuartzDebug option to show which parts of a window are actually transparent; on the standard windows only the corners are transparent, so for most of the window area the system can use the faster opaque calculations. I never filed a bug requesting a way for non-Apple code to do that because I didn't think it would be that generally useful - we make "transparent" windows to reproduce the odd shapes that Windows (the OS) provides for our virtual machines.
Unfortunately, I don't find any option in QuartzDebug to show which part of a window is transparent.
Do you know if it is possible to play with -displayInRectIgnoringOpacity: and friends to achive what Apple does on standard windows?
