Fix the problem of wrong mouse coordinates

Tried to fix the problem with the screen zooming down to the wrong mouse coordinates, now the mouse should click correctly! Since my monitor is only 1920x1080, I'm not sure if this problem still exists at 2k or higher resolutions, sorry about that! If you still have this problem after this patch, please do let me know and please play the game with 1360x768 to 1920x1080 resolutions and 100% to 125% zoom for now!
