I have a ryzen 2500U laptop running archlinux, after I upgrade the kernel from 5.1.16 to 5.2.x, firefox start to have those wired lines graphic glitch when browsing web pages, especially when browsing a page contain video.

This graphic glitch happens to every browser I tried: Chromium, qutebrowser(webkit engine), I tried to turn off hardware acceleration, it dose helped on Chromium, but not on firefox, so I guess it is a bug related to driver.

Currently I have 2 kernel installed on my laptop, one is the official kernel package from arhclinux with kernel version 5.1.16. I also compiled a 5.3.0 kernel using the archlinux official 5.3.0 kernel .config file.

I am new to linux, so I dont really know hot to debug this problem, but I'm willing to learn how if somebody give me a hint.
