Comment (by Klaas de Waal):

 A workaround, found in https://doc.qt.io/qt-5/wayland-and-qt.html, is to
 start the application with the **-platform xcb** option, as in:

 {{{
 mythtv-setup -platform xcb
 mythfrontend -platform xcb

 }}}
 This does actually work, both for the GUI and for video playback.
 However, as I understand it, this should not be necessary, because the
 documentation says:
 {{{
 Qt clients can run on any Wayland compositor, including Weston, the
 reference compositor developed as part of the Wayland project.
 }}}

 The default desktop in Fedora 32 is Gnome and that uses another
 compositor.

 When starting the Weston compositor in a separate session, after creating
 a configuration file that specifies X11 support:
 {{{
 [klaas at MyZen mythtv-master]$ cat  ~/.config/weston.ini
 [core]
 modules=xwayland.so

 }}}
 then mythtv-setup starts OK.

 If a Qt5 application should be able to run on Wayland directly without the
 X11 layer then we should figure out which Qt widgets, or which use of the
 Qt widgets, does cause the problems.

 If the statement "Qt clients can run on any Wayland compositor" does
 implicate "with the X11 layer" then the "-platform xcb" option can maybe
 built into mythtv as default.
