Comment 4 Eric Anholt 2008-06-26 15:54:33 UTC 
Same tiling issue as #16326, just seen in the glReadPixels path instead of glDrawPixels.

Comment 6 Shuang He 2008-07-13 23:35:36 UTC 
This seems the issue of glCopyTexImage2D. The following attached test case can be used to reproduce.

Comment 8 Eric Anholt 2008-07-17 15:15:54 UTC 
The demo, the regression test I put in piglit (copytexsubimage), and the supplied test case all work on our 945G system.
