I've been experiencing a seemingly identical issue for months too. I'm on an
Intel GPU, which suggests the problem is in kwin or a shared part of Mesa.
When window contents freeze, sometimes they are partially updated, triggering
an effect where only some segments/rectangles of the screen see into the
updated window. Also, I have the scroll wheel on the window title bar mapped to
change window opacity, and doing so always causes the full window to refresh
properly. Restarting kwin fixes the problem, temporarily. It would be
interesting if the original reporter sees this behavior too to further confirm
we're talking about the same problem.
I'm on Gentoo Linux amd64, kernel 4.11.8-gentoo (but this has been going on for
multiple kernel releases now), Core i7-3820QM.
