Created attachment 285017 [details] dmesg 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.

This bug looks similar to https://bugs.freedesktop.org/show_bug.cgi?id=111122 Could you try the various workarounds proposed there and see if it helps: - adding the iommu=pt kernel boot parameter (see https://wiki.archlinux.org/index.php/kernel_parameters#GRUB) - or using the AMD_DEBUG=nodcc environment variable (for instance, try adding a new line with "AMD_DEBUG=nodcc" in the /etc/environment file and reboot) - or updating Mesa to the latest version
