I still see this on Intel 14.04 machine with 4.4.0-64-generic #85~14.04.1-Ubuntu. It happens in fairly random way quite often after close and open of the laptop.
Images may either not display: http://askubuntu.com/questions/850754 /what-happened-to-my-dash-icons or show up with garbling as in attached screenshot. It may or may not be only the outer fullscreen restore button, as it always is at the moment. It showed in the upper right icon for awhile, it's like something is putting random junk in some random image memory location? ** Attachment added: "Screenshot" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1552750/+attachment/4831589/+files/badimg.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1552750 Title: i915 corruption in 4.4.0-9 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1552750/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
