Bug#523415: corrupted rendering

[Michal Pokrywka <wolfmoon@o2.pl>]

Hi, same bug on my workstation with debian unstable and

00:02.0 VGA compatible controller [0300]: Intel Corporation 82865G Integrated Graphics Controller [8086:2572] (rev 02)

with kernel: linux-image-2.6.29-1-686 and linux-image-2.6.29-2-686

with packages:
ii  libdrm-intel1                        2.4.9-2
ii  libdrm2                              2.4.9-2
ii  libgl1-mesa-dri                      7.4.1-1
ii  libgl1-mesa-glx                      7.4.1-1
ii  xserver-xorg                         1:7.4+1
ii  xserver-xorg-core                    2:1.6.1.901-2
ii  xserver-xorg-video-intel             2:2.7.1-1

x-org works with Option "NoDRI" "on", but is extremely sluggish :)

Cheers,
