[Openchrome-users] VN800

[Marcin Lewandowski]

Hi,

I've got Fujitsu Siemens Amilo Pro V2030 notebook, it has graphic card 
based on vn800 chipset. I use Ubuntu Dapper 6.06 (testing). I've 
compiled driver using that

instructions and it generally works, my desktop is snappy :) But when I 
started to use Blender (i need 3d software) which has OpenGL-made 
interface I can see many artifacts near mouse cursor when moving, and 
there are generally problems with refreshing. I don't think that is 
Blender-related problem because it worked well on vesa X driver (but I'm 
not sure, I'm not an X programmer :P). My glxinfo:

What I can do to solve the problem? Working with bad refreshing is hard.
