--- Comment #96 from Andre Maasikas <[email protected]> 2010-02-16 23:53:33 PST --- Maybe we should move hd4770 (RV740) issues to separate bug as I dont think other chips experience the same issue. RV740 seems not to render to GTT correctly afaik. You get a checkerboard pattern or stripes with half correct - half garbage. The easiest way for me to reproduce is using xmag under UMS. Just take a mag and you get a checkerboard. Using some screenshot app will also show this, just as in http://bugs.freedesktop.org/attachment.cgi?id=33228 Under KMS I can make screen corruption (x pixmaps?) happen with some opengl game with lots' of textures (Set to high/ultra) or also a minute or two with googleearth. I guess it starts when kms starts to evict & bring back buffers from vram to gtt. I guess we'r not programming/setting up rv740 correctly. Just to mark 2 other issues with rv740: it returns only half the occlusion query samples in ogl and pixmaps w<32 are disabbled altogether in dfs for this chip.
