I have found that the "out of the box" pi 5 software has the problem where
if you do something that causes another window to get in front of Mythtv,
(in my case, a terminal window I was switching to) then go back to mythtv,
the program would appear unresponsive, but I think it just loses keyboard
focus. I would have to kill and restart.

I also was having the problem where it wasn't using the right color depth
and  looked cheap. A user had figured out that it was a problem using it
under Wayland. There may be a fix or a  workaround for that by now in
Wayland or in v35 (Im still on 34). Anyway, I switched my pi to use X
instead of wayland and that seems to fix both of those problems.

HTH,

George
