Comment 56 for bug 745608

tabbernuk:

I recommend filing a new bug report using https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+filebug . While your issue looks similar to this bug report, you are seeing corruption in things that are not glyphs so your issue is different to this one...

Please post a link to your new bug report back here though!
