Update: I've noticed the location of the bar changes sometimes even without reboots. Don't know what causes it or how it's related. Here's a video of my screen flickering.
EDIT: I can't seem to play the video in my browser, but VLC should be able to play it. ** Attachment added: "Flickering screen" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2064017/+attachment/5832011/+files/flicker.mp4 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2064017 Title: Xserver Display flickers when mouse pointer is inside narrow horizontal range band (kernel related) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2064017/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
