23:48 < jcristau> ickle: any clue where 
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=635953#30 comes from?
[...]
09:38 < ickle> jcristau: looks like ddx, the clue is that we have two 
invariants in the batch
09:39 < ickle> (ignoring the 2D fluff) it looks like we do composite, video, 
composite
09:39 < ickle> only after the video, we do not reset the composite invariant 
meaning that we lookup the kernels and such from the video stream

Fix at
http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/commit/?id=1baff9f8cf79fdb4a5649eabcc66cf73487c873e

Not right now.  But when I'm back home then I can try to reproduce this
and get this over SSH.

Sounds roughly like .

Maybe that can help.

Bug#635953: GM965 display broken when using kino

[Ben Hutchings]

Package: linux-2.6
Version: 3.0.0-1
Severity: normal

I have just been using the kino DV editor after a pause of some
months.  It now sometimes triggers odd colour changes in other windows
(I have no idea how that would be - and it might well be an X bug).
Just a few minutes ago it seems to have triggered some more serious
error which left the screen blank.  The kernel logged the warnings
shown below.

Ben.
