forced resolution changes in last races led to sprint bug

As far as I know in 2 last races every participant with 21:9 monitor had black lines on the left and right just to change this resolution to 16:9. Which is fair but the thing is it also led to cursor bug where I could not even move properly because my character would sprint into opposite direction I wanted to. To fix this I had to play fullscreen which is really uncomfortable and it also can lead to death if u Alt-Tab accidentally because alttabbing back to the game takes a lot of time in fullscreen mode
