Priority: medium Bug ID: 58925 Assignee: dri-devel@lists.freedesktop.org Summary: compis/kwin crashes on nouveau due to msaa Severity: normal Classification: Unclassified OS: All Reporter: bobahu4@gmail.com Hardware: Other Status: NEW Version: XOrg CVS Component: General Product: DRI
Here compiz/kwin crashes when tries to run with weird assertion on msaa textures. Found that msaa can be swithced off with enviroment variable
http://cgit.freedesktop.org/mesa/mesa/commit/?id=1d0bf69f831e138a05a282e5974...
but GALLIUM_MSAA = 0 doesnt help at all.
so I edited dri_fill_st_visual in dri_screen.c to disable msaa at all
if (mode->sampleBuffers) { - stvis->samples = mode->samples; + stvis->samples = 1; }
Now compiz/kwin work fine.
