This is due to following commit: commit 14109abf285866ad4cd99d0cd16b0954a0a73a62 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Nov 10 11:17:23 2009 +0000 i915: Fix texture sampling coordinates. RENDER specifies that texels should sampled from the pixel centre. This corrects a number of failures in the cairo test suite and a few off-by-one bug reports. Grey border around images https://bugs.freedesktop.org/show_bug.cgi?id=21523 Note that the earlier attempt to fix this was subverted by the buggy use of 1x1R textures for solid sources -- which caused the majority of text to disappear.

One other bit of useful info when filing these conformance regressions is the error message from rendercheck. Thanks.

With this commit, only case triangles is fixed on both 945GM and 945GME. repeat is still failed. So I'd reopen the bug.

I've fixed one bug in the shader generation and reverted the centre-point sampling that was causing rendering errors elsewhere -- so I believe this bug to be fixed, except that rendercheck is reporting lots of unrelated errors on all platforms so I can't confirm. commit 5e04ded2bce4c135b57d391f5f4e24e030103e61 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Mon Nov 30 10:57:04 2009 +0000 i915: Fix missing texture offset for mask. commit cfcabc45140d19bfbfa4737c0a11cdbb042d11eb Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Mon Nov 30 13:58:30 2009 +0000 i915: Disable centre-point sampling.
