Could you post a dump with RADEON_DEBUG=noopt,vp,fp
New log attached. However there is something bad going on. There are two bugs affecting this game. This one and bug 60965, however when I reported them, this bug used to disappeared with RADEON_DEBUG=noopt and bug 60965 didn't. Now when I use RADEON_DEBUG=noopt, the corruption from bug 60965 is much worse and is all over the place. The change did happened with f6c061261885fed0c83c437e9459ba79618f1b3a is the first bad commit commit f6c061261885fed0c83c437e9459ba79618f1b3a Author: Brian Paul brianp@vmware.com Date: Fri Mar 1 15:16:15 2013 -0700
st/mesa: convert ir_triop_lrp to TGSI_OPCODE_LRP
AFAICT, all gallium drivers implement TGSI_OPCODE_LRP. Tested with softpipe, llvmpipe, svga drivers.

without RADEON_DEBUG=noopt the corruption is still the same, so my guess is that r300 compiler somehow doesn't like TGSI_OPCODE_LRP, optimizes is away a little bit, but not completely.
