Bug#470581: xserver-xorg-video-ati: X exit while running xv apps (mplayer, totem, etc) when using randr sidebyside monitors and compiz

[Alban Browaeys]

Package: xserver-xorg-video-ati
Severity: normal

Tracing with gdb from remote host I get only:
Program exited with code 0352.
when the "crash" happens (no freeze only X stop and gdm is fired up).

This happens when running mplayer/totem with xv so I first though it was
a critical bug in the driver. By cheer luck I found out it was because
compiz check max texture size against width and height to avoid issues
..... but randr changes those width and height on the fly afterwards.
And bad things happens. I had a 1280x800 LVDS and a 800x600 TV which
made up 2080 just above my  GL_MAX_TEXTURE_SIZE of 2048 (radeon mobility
M25 X600 rev 0).

Sorry if you find out that this is not up to the driver to disable dri
on the fly if max texture is reached. Please forward it to compiz if so.

I made the test with 1:6.8.1~git20080310.38606b08-1 and then with source
(which I currently use thus the lack of version info). Though the issue
affects all versions at least in 6.8 branch.

Best regards
Alban
