Makemkv dialogs not showing properly on Big Sur(ly)

[cappy2112]

MakeMKV 1.17.3, BigSur 11.7.4, M1 MacMini

When Makemkv finished ripping, the dialog which shows that the rip had finished was hidden.
It was actually shrunken, and on the other monitor from where the program was running.
See screenshot.

When I clicked on the "About" dialog to get the program version, the shrunken dialog happened again.
