Fun fact 4: in 2020 KDE's window manager ignores your monitor's refresh rate. If you have a monitor that runs at a different rate than 60hz you have to manually create a config file to manually set the refresh rate. Good luck if you're using a laptop on an external monitor.
@animeirl what do you mean?
@mia it was last I tried, it might have been fixed recently though, it's been a few months since I've used KDE.
@animeirl that sucks. not a problem with wayland though, i guess?
