Visual artifacts on greeter screen and in certain apps like Gimp

Getting weird visual artifacts on the greeter screen:


The little purple cells move around on the greeter login prompt.

I also get this artifacting in Gimp on certain controls, and even on certain websites.
I’ll do my best to provide further documentation. I have installed and uninstalled a great number of packages associated with i3, bspwm, xmonad, and mate recently while checking those out, but I’ve also upgraded all of my packages consistently. Surely possible I caused this issue myself somehow.

What graphics card and drivers are you using?

Could it be you have both Picom and Compton installed and conflicting?

If you are only running xfce perhaps you can try removing them.

Please give better system info for help, right now it’s a bit a guessing :dart:

Use inxi -Fxxc0z | eos-sendlog and post the link here so we can have a look.

I upgraded my system, and as of now the artifacting is gone! Yay. My apologies for the low effort put into providing system info and description of the problem w/ evidence. I was quite busy at the time. As a big fan of EOS I would like to thank you for showing up to try and help. I’ll return to this thread if the problem persists.

Well, that didn’t take long. @s4ndm4n @Zircon34

Still happening.

Can you check in pacman whether picom or Compton are still installed? Multiple compositors can potentially conflict with each other.

inxi -Gxx | grep compositor
Display: x11 server: X.org 1.21.1.1 compositor: xfwm4 driver: loaded: amdgpu,ati
pacman -Qe | grep picom
picom-jonaburg-git 0.1-4
pacman -Qe | grep compton

(Compton grep search returns nothing)

Are you still using picom or can remove? You mentioned you deleted your wm. Maybe there is some conflicting configs with xfwm. Maybe not but could be worth a try. Other thing that comes to my mind is graphics card driver.

Just uninstalled picom and rebooted. The problem persists. I’ll look into downgrading my graphics driver or changing

To be honest, I don’t know anything about AMD/Radeon graphics cards. I thought that the drivers are open source and implemented in the kernel. First thing I would try is boot either lts then normal kernel. Second thing, I found a post on arch Linux. The users say they had to install two packages from AUR. The thread can be found here

https://bbs.archlinux.org/viewtopic.php?id=265282

They mention installs of linux-firmware-git and mesa-git from AUR. Would be good to check with someone knowledgeable about these card. I think I saw a post from @Elloquin about this AMD Radeon RX 6700 XT card. I suggest to do a forum search and tag them here.

Thank you for sleuthing.
I wasn’t able to install linux-firmware-git due to PGP error
gpg: WARNING: unsafe permissions on homedir '/home/myuser/.gnupg'
Even after running
chown -R myuser ~/.gnupg/
But, I was able to install mesa-git and it seems to have fixed my problem for real this time.
If it’s still fixed tomorrow evening I’ll mark this as solved.

Problem is still here. Not sure how to proceed with the linux-firmware-git installation issue. I’ll do what you mentioned and contact someone in the know about my GPU
