[2020] Cannot pause with keyboard on Linux

Athas said: Neither the space bar nor the keyboard Pause key pauses CK3 for me, playing on Linux. Shouldn't at least one of these work?

I would have thought so, yes. Unfortunately I can't run this game on my Linux installation; the MacOS version is very similar and space bar works fine there though.

What distro is this?

Do you have any unusual sort of keyboard setup or layout?
