--- Comment #9 from Matteo Italia matteo@mitalia.net --- I didn't check the code, but when seeing the result I thought that maybe the screen DC is "more magic" because it has to interact with X and/or the compositor in some way. If that's of any use, on all the machines where I tested the bug I use KWin as compositing window manager.
