Display problem with Intel 852 chip and FC2

[Jörg-Rüdiger Hill]

I have tried to install FC2 on a Toshiba Satellite notebook which uses an 
Intel 852 chip for graphics. The installation went smoothly, the chip was 
detected and X was configured automatically to use the i810 driver and 3D 
hardware acceleration. However, whenever I run an OpenGL application there is 
a square slightly larger than the mouse pointer which is kind of copied from 
the point the mouse pointer was a few seconds ago and which moves with the 
mouse pointer. Effectively, this makes it impossible to pick anything with 
the mouse.
If I turn hardware acceleration off by commenting out the dri module line in 
xorg.conf everything works as it should be (although without 3D acceleration) 
and the effect described above does not show up. Unfortunately, the notebook 
is supposed to be used as a demo machine for an OpenGL application. I have 
tried the few options available for the i810 driver without making any 
difference. In particular, enabling a software cursor just turns off hardware 
acceleration, which is of no use to me. I can't find any description of a 
problem like this on the net. It seems that people have no problems with the 
i810 driver.
Has anybody seen such a problem and knows what to do to fix it ?
