When I watch a video on youtube at a higher resolution, the image quality sometimes breaks down. It looks jagged.
On Chrome I don’t have similar problems, only in Brave.
Unfortunately I can’t make a screenshot, I’ll give you a picture that looks similar.
System:
Windows 10
Radeon RX 580, drivers 19.5.2
