i've been seeing slowness on radeon since at least 2015 particular
when switching virtual desktops. it acts as if the X server and
the applications are swapped out, almost, the re-draw is so slow
it happens pretty infrequently for me, and i have not found any
cause in my various investigations.
i wonder if setting HZ=1000 makes the problem less severe.
