If you can reproduce at will, an apitrace would be nice. (30 mins would be ridiculous though.) I'm not aware of any opcode emission bugs with nvc0 cards. Another thing to try would be to make a debug mesa build, and run the game with NV50_PROG_OPTIMIZE=0 -- that turns off all shader code optimizations, which would make it even less likely to hit a "weird" instruction emission situation. This might also be some vram corruption/buffer copy issues/something else unrelated to opcode emission...</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
