Wild, wild, wild.... I was setting up to get a screenshot and very
rapidly did a whole bunch of large copies from Nemo to other Nemo
windows. I got the often small window 'preparing to copy" which can
take a few minutes to clear, then all five of the Nemo windows went
gray and stopped responding. I waited a long time and they didn't
recover so I decided to just stop them in htop. I think I was stopping
the third window when they all disappeared [maybe that was the hung
BUT - when I went to start them again I noticed that the long standing
problem graphics I have been talking about were GONE!!! So, maybe
there was something about Nemo that was causing it? I had never
stopped a hung Nemo via a CLI or htop before - that was new. Anyway,
by accident, I seemed to have solved something that has survived
multiple reboots, and I have no clue why it went away. I don't want to
reboot just yet but I hope it does not again reappear when I do
reboot. I'd like to consider this closed, but if it does come back
I'll mention it again.
I do appreciate your responses in helping to solve this, and if anyone
has a clue why stopping a hung Nemo may have fixed it, please tell
