Yeah I feared that, the bug with mouse sensitivity forced me to change a function in the core of the gui, which is very dangerous, and I was almost sure there would be a problem... Maybe I should have taken more time to check things. Well I got a cold + some covid from a friend lately, so it's a little hard currently, I'll go and check for this covid a little later.
So at least I know where the problem comes from, even if it's not obvious to fix, I'll look into it later.
Meanwhile, use the keyboard for the game selection !
