AMD Ryzen Vega 11 tearing issue (amdgpu)?
by kukibl from LinuxQuestions.org on (#56ECP)
Hello Slackers!
I've been off Linux for quite long/some time. Now with recently custom-built PC with AMD Ryzen, I have decided to try to get back and use it as my main system at home.
I have installed Slackware current using latest AlienBob's iso image. Everything works fine (UEFI thing and eLilo were actually an adventure), except there is issue with screen tearing in Firefox and SeaMonkey, mainly when I open dynamic pages like YouTube. Bunch of horizontal lines would appear in the window and something rendering it completely unusable. You can see the screenshot here: https://i.imgur.com/q9J4ayW.png
I have researched a little bit and found out wiki pages for AMD GPU at Gentoo and Arch, but the tips I have found there are not working for me.
Some details: it is custom built PC with AMD Ryzen 5 3400 GPU (with Vega 11 integrated graphics). Slackware64-current with all the latest updates. lspci shows this:

Kernel driver in use: amdgpu
Kernel modules: amdgpuUsing the tips found online, I have also made configuration file for Xorg, but without any results (there are no other configurations for Xorg except this one, because it started without any issue):
Code:bash-5.0# pwd
/etc/X11/xorg.conf.d
bash-5.0# cat 20-amdgpu.conf
Section "Device"
Identifier "AMD"
Driver "amdgpu"
Option "TearFree" "on"
Option "DRI" "3"
Option "AccelMethod" "glamor"
EndSectionFor comparison: I booted Xubunutu 20.04 and the issue is present there, but much much less (rarely noticeable). When I disable smooth scrolling in Firefox, on Xubuntu this tearing is neglect-able, but on Slackware does not make any difference.
Any tip/help would be appreciated. Thank you.
