[Bug 315436] [NEW] Regular lag of video playback and 3D graphics with intel GM45

[ThyMythos]

Public bug reported:

Binary package hint: xserver-xorg-video-intel

I have a Dell Latitude E6500 (more info:
http://wiki.ubuntu.com/LaptopTestingTeam/DellLatitudeE6500).

When playing back videos or playing 3D games I experience regular lags
of the display output about every 10 seconds. It happens independant of
the video output driver (XVideo, OpenGL, accelerated and unaccelerated)
and of the player (VLC, flash plugin on youtube) and with every 3D game.
The sound is not affected.

Installed packages:

-  libdrm-intel1      2.4.3+git20081216.c86d431f-0ubuntu0tormod1~intrepid
-  xserver-xorg-video-intel     2:2.5.99.1+git20090102+xf86-video-intel-2.6-branch.fac43181-0ubuntu0tormod

But it seems independant of the exact version of these packages as it
also happend with earlier versions of Intrepid.
