Public bug reported: Display starts to blink and present corrupted lines after return from power save.
This is related to https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2083650. The strange is that recording the display (video) the corruption doesn't appear. So, I recorded with a external camera to show the case. As work around that I discovered: unplugging and plugin again the display worked around the issue.
