Hey! I have this minecraft bug since begining decembre. Every time i play minecaft in the version 1.14.x 1.15.x 1.16.x i watch at the top left every few seconds. I normaly play in the 1.8 and there is no problem. If i use a pvp client like badlion or lunar the bug is still there. This bug has nothing to do with my mouse because i normaly use a corsair harpoon wireless and switched to the roccat kone emp because my old mouse was broken and the bug is still there. (sorry for my bad english and here is a video from the bug )
