I will detail the steps to reproduce once I figure them out: Usually I have a
firefox window open, and a bunch of konsole windows. The konsole windows will
usually fail to show the very last line, and firefox will have rectangular
areas of the screen where things are left as they were before switching to the
firefox Desktop. The other user who complained on opensuse@opensuse.org
mentioned buttons
which were not drawn, but were functional.

kernel-default-4.4.46-11.1 is the last one that worked.
