Description WuNian 2008-06-02 00:57:39 UTC 
Created attachment 16863 [details]
test case

The attached test case creates texture which every 4x4 grid has same color. Then it transfers Texture matrix and specify texcoord with glTexCoord4d. After these coordinate transfer, the texture should be rendered as original texture, i.e. every 4x4 grid has same color.
But now the destination pixels is rendered incorrect that every 2x2 grid has same color.

Remove i915 driver, the bug does not exist. So it is i915 driver bug. 
Also exists with i965.

The bug does not exist with i965 driver.
And this is a regression which occured at 2nd, April.
