Is this a regression? If so, can you bisect mesa to see when it broke? (In reply to comment #3) > Is this a regression?

As a temporary solution disable "Full screen glow effect" in game options. I believe the problems is with inverted coordinates when rendering to texture with FBOs. I hope to get it fixed before mesa 7.6 release. *** Bug 25156 has been marked as a duplicate of this bug. *** The classic r300 driver has been abandoned long ago. It was replaced by the Gallium driver r300g. If you have issues with r300g please file a new bug report with component Drivers/Gallium/r300 Thanks. |
