[Xorg-driver-geode] "Allocate video memory with exaOffscreenAlloc" causes visual corruption with Xv

[Daniel Drake]

Hi Hunk,

The following commit causes a regression:

    Allocate video memory with exaOffscreenAlloc


The regression is detailed here:
https://bugs.freedesktop.org/show_bug.cgi?id=33004

It can be trivially reproduced with:
 # gst-launch videotestsrc ! xvimagesink
Try opening/closing that several times, and dragging the window around
the screen. You'll see visual artifacts in other windows, mouse cursor
corruption, etc.

Thanks,
Daniel
