I would have to kill and restart.

The only way to bring it back is to kill and restart the mythfrontend. (continue reading below)

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.

I have not found a distro running Wayland that works completely right
for Mythfrontend.  So I use the --platform xcb option when it's
launched.
