xorg.conf
When running a program using the DRI on a screen with an interlaced
video mode, the screen freezes periodically, i.e. every screen update
stops, even the movement of the cursor. This occurs approximately
every 10 seconds and lasts for about half a second. Everything else,
e.g. audio output, appears to run normally.
The symptoms apparently are the same as those of <a class="bz_bug_link

title="RESOLVED FIXED - GM965:opengl playback jerky (glxgears, vlc, etc) [io stutters?]"
href="show_bug.cgi?id=45674">bug 45674</a>, but I'm
seeing this issue only when using an interlaced video mode.
System environment:
-- chipset: 945GSE
-- system architecture: 32-bit
-- xf86-video-intel: 2.19.0
-- xserver: 1.12.4
-- mesa: 8.0.5
-- libdrm: 2.4.40
-- kernel: 3.7.1
-- Linux distribution: Debian Wheezy (kernel from experimental)
-- Machine or mobo model: Intel D945GSEJT
-- Display connector: VGA
Reproducing steps:
- Start X with an interlaced video mode (see xorg.conf for the
Modeline I'm using)
- Make sure that the DRI is in use (e.g. by activating desktop
effects in KDE)
- Start a program which countinously produces output or watch a
video or just move the cursor around</pre>
