Ok this should be hitting us pretty soon via upstream, it looks like it will be in -rc5 as it is on the intel-fixes branch already. I will pull it in temporarily for futher testing, expecting it to go on on the next rebase. ** Changed in: linux (Ubuntu) Status: Triaged => Fix Committed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/711568 Title: Dithering regression on Intel graphics with .38 Natty kernel -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

llstarks, thanks for interfacing with upstream directly. Since it's pinpointed to the kernel drm and since we've got a patch now, the kernel team can take it from here. ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/711568 Title: Dithering regression on Intel graphics with .38 Natty kernel -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
