Bug#368063: xserver-xorg: BackingStore causes some areas not to be redrawn with a Radeon Mobility M6
Package: xserver-xorg
Version: 1:7.0.18
Severity: normal
Hi,
I've had the BackingStore option enabled for a long time in my xorg.conf.
Approximatively when I upgraded to xorg 7, some areas of the screen started not
to be redranwn. In particular, when I close a window, the portion of the window
below it is often left as a black (or white) square.
It took me some time to understand that it came from the BackingStore option
of my xorg.conf (the problem vanishes if I remove this option).
Thanks for your work.
Cheers,
Samuel.
