[1.5M]
(you won't see any problem until you run -rc3+ kernel).

I've bisected it[2] and found offending commit[1].
My hardware is HP Compaq 2510p laptop:
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)

Do you need more info?

Thanks!

068143d38804825d59d951a192cfadd2e22f457d is the first bad commit
commit 068143d38804825d59d951a192cfadd2e22f457d
Date: Mon Oct 5 09:58:02 2009 +1000
drm/fb: add setcmap and fix 8-bit support.
This adds support for the setcmap api and fixes the 8bpp
support at least on radeon hardware. It adds a new load_lut
hook which can be called once the color map is setup.

Hi!

After syncing git tree to bd381934bf13ccb1af2813ae26c6fe00ec85d254
I've experienced pixel color corruption in Xorg.
Some of pixels (not all) have abnormal colors seen on images like this:

(you won't see any problem until you run -rc3+ kernel).

I've bisected it[2] and found offending commit[1].
My hardware is HP Compaq 2510p laptop:
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)

Do you need more info?

Thanks!
