--- Comment #47 from Jonathan Neufeld <supp...@extollit.com> ---
This has been happening to me for several years, ever since I switched from
Windows to Linux. It happened to me on Kubuntu 15.10, 16.04 and now 20.04. I
think it can affect any application, it doesn't discriminate. A few years ago
researching this issue I remember stumbling upon a suggestion that it was due
to a conflict between the Qt framework and running Java applications, something
about Java applications not invalidating some video-related caches and thus
causes problems to prop-up elsewhere.
I resolve this by opening the Compositor settings and then toggling a radio
button off and then on again, just so that the Apply button becomes enabled and
allows me to trigger something. Perhaps this restarts the compositor or
perhaps it does something less destructive, I don't know, but this has been the
workaround I have been using several times per week for several years. It
takes me only 20 seconds each time, but those 20 seconds add-up and so does the
frustration.
Also I am using an nVidia card, and the issue occurred on two different cards,
both brand new. I don't know how the internals work, but I would be very
surprised if this issue turned-out to be hardware-related.
