This bug has been in the game for a while now. If you are on windows (Idk if this applies to other OS as well, but it applies for windows) and switch desktops (with ctrl+win+right/ctrl+win+left (this requires having multiple desktops, you can create desktops with win+tab and then pressing new desktop)) while in a game (for example the practice range), when coming back to the game and pressing escape, your mouse gets reset to the middle of the screen every couple of frames and is invisible. After a coupe of seconds, the bug fixes itself, but it’s pretty annoying for those seconds
