Possibly due to focus-maanagement (and how linux allows for exclusive input capture), keyboard stopped working after alt-tab probably during game loading (only once). I preventively switched to windowed-borderless to avoid possible problems in the future.

Mouse is delayed, especially in the menu. Less noticable in the game.

Inside newspapers shop UI and in the disguise shops UIs.

When game slows down once (e.g. after opening disguises UI) it lags until it's restarted.
