When you move in the game all the textures, particularly the ground ones, start shifting around making it almost unusable.

Does r600g from mesa git master work any better?

Comment 2 Mark 2012-01-02 09:19:45 UTC

Yes it does, closing!

Comment 3 Mark 2012-01-02 10:06:21 UTC

Whilst much improved, there are frequent rendering glitches still.

Comment 4 Michel Dänzer 2012-01-03 10:31:35 UTC

Are those glitches a subset of the original ones, or new ones?

If the former, feel free to reopen this report with details about what the remaining glitches are. Otherwise, the new glitches should be tracked in a separate report.

I tested HEAD again to see if any performance enhancements were around, and this problem was back, i did a few git bisects and found this commit.

This looks like an issue with interpolation. I'm pretty sure it's been fixed, because interpolation qualifiers were reworked after the last feedback. Closing.
