[SOLVED] Graphical Artifacts

General system Newbie
1

I have some weird graphical glitches since december and since then it only gets worse. The issue is very apparent when I read pdfs in Okular, but appears randomly when using other programs as well as when system idles for a few seconds

I usually use zen kernel, but after reading about similar problem on one of the forums, where it was advised to use lts kernel, I used that and issue,although still existant, was very rare. But whenever I launch zen kernel, the session is basically unusable.

However, since last lts update, these artifacts consistently appear on lts kernel as well.

I use KDE Plasma 6 on Wayland, however I downloaded Gnome DE for testing purposes and issue persists there as well

Issue doesn’t appear in Plasma on X11 (even with zen kernel)

I also tried changing refresh rate of display from dynamic to stable and from 144 to 60 Hz, neither one had any effect on the issue

When I disable integrated GPU in bios and run only discrete Nvidia card, issue also doesn’t appear

I am at a loss and have no idea if this issue is with wayland or AMD driver of integrated gpu or the particular mixture of both or something else entirely, and I dont even know where to look for clues, in which logs etc;

I am ready to provide any additional info about the system if needed and send video showcasing the issue

I see that you have a Nvidia GPU. What’s the output of pacman -Qs nvidia? How did you install the drivers?

What’s the output of:

inxi -Fxxc0z

Other info may be needed, so please check this link as well.

PS: In the future, on any forum where you’re asking for help related to your system’s hardware, most of the above is actually useless data/info. It’s better to post something that shows driver and/or firmware versions rather than software versions.

I am sorry, I wasn’t sure whether it is a hardware or software issue, therefore I included what I thought might be relevant

If I remember correctly, I installed nvidia-open-dkms from aur, though it might’ve been from official repo, I don’t remember for certain.
(But I’m almost certain it was AUR since I use zen kernel and therefore use dkms version)

Either way, I don’t think the nvidia is the issue since these glitches do not appear when using only dGPU, as I mentioned in the first post

Oh, no. Nothing to apologise about, I’m just letting you know so that you can include more detailed info from the start, is all.

As for this command, I think a better (less bloated) command is:

pacman -Q | grep -A 0 -E "(nvidia)"

Or if you want to include other info for other hardware/software:

pacman -Q | grep -A 0 -E "(nvidia|amd|intel|linux|headers)"

No need for a description of the package.

Should I re-upload this log then?

No. That is addressed to @winnyace only. The log I asked for actually includes all of that and then some, so no need at all.

Based on your system specs and what you’ve tried so far, it’s very likely a Wayland issue, or a combination of Wayland and the DEs you have installed.

Or, it could be a user settings issue.
Try creating another user, log into it and check if you still experience the same artifacts using KDE Wayland and your usual kernel, enabled hardware, and so on — so like usual.

Another test is to try one more Wayland session, but in Hyprland instead.

PS: Also, you may want to remove Gnome to avoid it causing issues with your KDE settings.
Long story short: They don’t like each other.

Following on from this

try log in under x11

Something that seems to cause a lot of random issues

I would just remove as multiple DE is a good way to get issues

12

Yes, I deleted gnome after testing since I know about theim not liking each other; I only installed it for testing.

As for hyprland, as far as I can tell I don’t see the issue appearing

I also tried new user in KDE and looks like issue doesnt appear there as well

With that, it seems like there’s some issue with my customizations. Perhaps kvantum manager for transparency? Why did I have glitches in Gnome then… Interesting

Update: No, actually on new user in KDE it appears as well, after a few minutes in session it started appearing

13

I would guess this is what caused your issues than, I don’t use kvantum in any themes as I have noticed it causing issues in a few apps and its purely for asthetics, as much as I love a nice looking envirpment I prefer it to work

This is an example of why even though Arch is a rolling distro, and you don’t need to reinstall, some people do because reinstalling usually get rids of all these little hiccups that build up over time.

That said: You don’t need to do that, just try disabling some of your customisations to see what helps.

Another option is to create a new user account with admin privileges, copy your config files to a backup folder, log into the new user, delete the old one, then recreate the old one with the same exact name. Finally, copy a few files back to it — the non-problematic ones.

15

Hmm. Post the output of this command, then. Wanna see something more specific.

pacman -Q | grep -A 0 -E "(nvidia|amd|intel|linux|headers|plasma)"

After deleting kvantum and applying default theme it appears that the issue disappeard for me. Thanks for everyone’s help here, I’ll mark it as solved

you can still probably use the theme you were using without the kvantum settings, I often use them this way just for the colours
