So I noticed this quite a while ago, but thought it was just a smudge on my screen..
When watching videos on YouTube in full Screen, there are weird lines at the top of the screen, always in the exact same position.
I tested this with other Web Browsers (Google Chrome, Firefox and Vivaldi), and other video streaming sites (Disney+, Crunchyroll, and Hi-Dive), and the issue appears to be exclusive to YouTube with Opera GX.
Is this just me? Or is this happening to everyone? It's very minor, and not noticeable most of the time.. But just thought I'd ask..
I made a post on Reddit about this 3 days ago, but now another much longer line is now there as well.
