Priority: medium Bug ID: 60965 Assignee: dri-devel@lists.freedesktop.org Summary: [r300g] Anno1701: flickering colorful corruption over some models Severity: normal Classification: Unclassified OS: All Reporter: pavel.ondracka@email.cz Hardware: Other Status: NEW Version: git Component: Drivers/Gallium/r300 Product: Mesa

In Anno1701, there are flickering colorful spots over some models. It looks similar to the bug 60552, except the spots are colorful instead of black and they don't go away with RADEON_DEBUG=noopt.

Setting Wine to use ARB shader rendering backend instead of GLSL makes the problem go away indicating another bug in the shader compiler.

Apitrace here http://pavel.ondracka.cz/Anno1701.trace (renders fine with proprietary NVIDIA drivers).
