Youtube fullscreen scrollbars showing up

Hello!
i’m having some weird problem when i go into youtube fullscreen, 2 scrollbars , one bellow and one on the right side keep showing without going away wich blocks some view of the videos i watch.

sorry for the pic it might be a little hard to see. but this is how it looks like on youtube fullscreen.
Does anyone know how to get rid of thease annoying bars?. i’ve tried looking into the settings but i can’t find anything related to my problem.
This does not happen on chrome, only brave

Thank you! - Zine

i managed to fix this problem, it was one of my extentions, no clue why, never happend before but atleast its fixed.

Can someone lock this post?
