Created attachment 25371 [details] google mail image FireFox (version: 3.5 beta 4) displays grey border arround some images, like the html view in google mail, company image. This work using xaa with same FireFox version without border. I run on i915, and fedora 11 preview release with driver-2.7, kms is enabled.
Created attachment 25729 [details] image open in firefox for test Open in FireFox, you see grey border top and left for image size fit screen properties. On clicking (image original size) everything is ok. Fav-Icon (left of address) also have gray border.

Same problem here. I have observed top and left borders on images and have confirmed that it happens when the image is scaled. I believe I have seen the borders in colors other than grey, too. I am using Fedora 11 and Intel graphics.
I've tried Option "NoAccel" "true" and Option "AccelMethod" "XAA" in the "Device" section of xorg.conf. Neither modification resolves the problem for me.
This looks like the texture sampling bug coupled with bug 17933. The first part I believe to be fixed with 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. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> The second requires a little more fixes spread around the packages a little debate... But for the time being I believe this bug reduces to be a dup of 17933. *** This bug has been marked as a duplicate of bug 17933 ***
The problem is persisting with xorg-x11-drv-intel-2.11.0-4 and firefox-3.6.3-4 on a Fedora 13 system.

Yes, that patch was found to cause a few problems and so I had to revert before 2.11. However, 2.12 fixes it for sure! :) commit dc402334f4e9b0de624bc89cd77eae4ec7cf1708 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Jun 1 23:03:19 2010 +0100 i915: Centre sampling. Use centre sampling of textures to match pixman, and remove numerous off-by-one and visual artefacts when rendering. The classic example for this is cairo/text/xcomposite-projection where the edge of the rotated rectangle is jaggy due to the incorrect sample position. Fixes: Bug 16917 - [i915] Blur on y-axis also when only x-axis is scaled billiear https://bugs.freedesktop.org/show_bug.cgi?id=16917 And about 15 tests from the Cairo test suite.
