Public bug reported:
Hi, I installed Ubuntu and found I have graphical corruption at the top of the
screen, few horizontal stripes. If some window lose focus, it can be covered by
them. Window with focus DOES cover it. Another user doesn't see it (the bug
doesn't occur).
It came after I upgraded intel GPU drivers via ubuntu X-SWAT, so I uninstalled
them using ppa-purge, but it didn't help.
