Hello there. I originally posted this on gaming, but since I am convinced that it has nothing to do with game itself, there it goes.
I stumbled upon a problem that when I increase window size or even go fullscreen in minecraft framerate gradually drops, until 15-20 in fullscreen, although ingame debug overlay still shows same amount of fps. (Tried running 120 fps: feels exactly the same (20))
I tried to run different versions. Same result. The only thing I suspect now is Xorg/mesa messing with resolution/frames or so, idk.
Dependancies (if necessary):

I also tried to play in xorg.conf.d with different options (TearFree and everything related to vsync). Nothing seemed changed (I hope I tried it correct way) .
How do I fix it?
