Cursor problem, unusual and not even addons can fix it...?

Mouse Cursor Has A "White L Shaped Line" Next To It

Greetings, So I logged into WoW yesterday and my mouse cursor has a “white L” shaped line next to it. I have tried disabling add ons, reinstalling game, scan and repairing game. Nothing is fixing it and no one I know has this issue also. I found a user on reddit who also has this issue. Weirdly if I change the mouse size in game to anything but default, it goes away. However no matter what I do the default size appears this way. Update: On WoW classic the issue isn’t there but on retail it is…
