Hi: I've been attempting to debug a bug that recently entered Ubuntu jaunty [1] related to MythTV. It seems that a whole slew of X BadMatch errors and RenderBadPicture errors are thrown out whenever a QWidget show call is used. Using git-bisect, I came to the conclusion it got introduced at this commit in the xorg-server 1.6 branch:
commit 8b967b24690cb072fc37c463eceb2b886cef80c4 Author: Eric Anholt <[email protected]> Date: Mon Feb 2 10:13:46 2009 -0800 glx: Don't match fbconfigs to visuals with mismatched channel masks. This fixes at least one known bug, where the depth 32 visual would end up with a depth 24 fbconfig attached, angering compiz. (cherry picked from commit 5100d829a4d71ce4a9fbc2b81694a1fb90066ccf) Signed-off-by: Keith Packard <[email protected]> Having no in depth knowledge of this code, I'm at a bit of a loss of whether to point fingers at QT3 that some patch is necessary, or if this is a genuine problem with Xorg.
