Comment 2 Brian Paul 2010-09-21 13:06:44 UTC 
Fixed with Mesa commit b3a647276e5fae570628826961c9b86612c2a2c6 (the sprite-coord branch).
Comment 3 Vinson Lee 2010-09-21 14:07:13 UTC 
mesa: 45d10c7d5910ada45b3bf7c34f9fb98c80c72664 (master)

Verified fixed.


mesa: 2606105cc5c452f32e3b3418e474e3c71702534a (7.9)

Still fails.
Comment 4 Keith Whitwell 2010-09-22 00:46:20 UTC 
For 7.9 we can just re-enable the old draw module path, which should fix things (assuming we don't want to merge the pointsprite branch to 7.9).
Comment 5 Brian Paul 2010-09-22 07:26:01 UTC 
OK, 7.9 is now fixed w/ commit 3cdfc6252394541e28e8290b7539bd1b132ea004.
