This may be a driver problem. I am not running Wayland, but I tried 
setting Window Scaling to 2x (Appearance-> settings) and mythfrontend 
works fine (NVidia with 4K monitor).

You could alternatively adjust the resolution if it is too small by 
setting a Custom DPI (Appearance-> Fonts). By setting this higher, 
windows, fonts, etc. are shown larger, but mythfrontend would not be 
affected.

Another option is changing resolution to 1920x1080. I would think this 
would be the same as scaling 2x.
