On the PC it happened on instead of fresh install I restored a partition image from one
of the several F27>F28 upgrade "successes". Plasma is exceedingly lethargic on a single
core 2.8GHz P4 with 1G RAM and compositing unable to be disabled[1]. It's producing a
black systemsettings window simply opening it:
t2240:> inxi -v1xx | head -n(G)

(Raising RAM from 1.0G to 1.5G makes no apparent difference)
(All works as expected booted instead to F27.)
This P4 also produces black window simply opening systemsettings5:

I repeated on different host what I did prior to original thread post:

(still black window systemsettings5)
FWIW, host t2240 with openSUSE TW and Plasma 5.50 trying to figure out whether this
trouble is Fedora or upstream blacks the whole session, while IceWM works as expected.
