Notorious input lag

As in my other post (I think it is better to keep the posts separate because they are different problems) Minetest on Linux has a strange input lag in the mouse, it is not very big but it is very noticeable for a game like Minecraft, it gives me headaches when playing with that input lag.

I tried to activate the mouse "smoothing" and although I would say it helps a little, it doesn't really fix it, it just camouflages it and gives a weird sliding effect on the mouse.

As I already mentioned, this problem is exclusive of Minetest in Linux, in Windows I don't suffer from any problem.

I consider that these problems are Nvidia's propietary drivers fault, I was really investigating a lot this problem before posting this here but I didn't find anything, just some unrelated issues in Github.
