Hi I've updated to 3.4 kernel, and now I'm noticing slight changes in brightness on colorful images. It seems the change is mostly visibly on 'darker' images i.e. it's not really visible on white background. When I reboot back to 3.3 kernel - brightness changes are gone - so I do not suspect hw fault of my T61 display. I guess once in past there has been already such bug, so this problem seems to me like reintroducing the same problem again. xorg-x11-server-Xorg-1.12.1-1.fc18.x86_64 with SNA intel driver build from git repo. T61, 965GM Is this a know issue ? Is bisect needed ? Zdenek
