Public bug reported: I'm running Ubuntu 13.10 on a MacBookAir5,2. The machine has an Intel HD Graphics 4000 processor.
Every few minutes, a bunch of garbage blank lines flickers onto the screen for a fraction of a second and then vanishes. I also saw this running 13.04 on the same machine, but never before that. It's impossible for me to capture a screenshot since it's completely unpredictable when this will happen. But it's pretty distracting. ** Affects: xserver-xorg-video-intel (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1177358 Title: black line garbage flickers onto screen every few minutes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1177358/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
