We love to praise linux constantly and tell everyone to change to it (they should) but what are your biggest annoyances ?
Mine would be, installing software (made even more complex by flatpaks being added, among the 5 other ways there already were to install software) and probably wifi power management issues.
I just ran into a new crop of problems with Linux games.
Apparently Unity 5.4.0 has a bug where it will crash (or rather close the game) if Chrome is running. (Or any Electron app like oh, say … Steam) Kudos to Unity for fixing it, but shame a bunch of old Linux-native games will never get fixed.
