Cursor shrinks after ALT+TAB

Someone reported this a couple of years ago https://boards.na.leagueoflegends.com/en/c/bug-report/71geA8EJ-cursor-shrinks-after-alttab-fix In summary, when I alt+tab during a game, and then return to the game, my cursor has shrunk. The cursor does go back to normal size if I switch on/off colorblind mode, but this needs to be done everytime I alt+tab. This is a fairly old bug. I would really appreciate a fix.
