Kwin_wayland spams error log when alt tabbing

Help

Hi there, hope this is the right place to talk about this. I’ve noticed that whenever I alt-tab and hold it so that the thumbnail preview comes up my journal gets spammed by kwin_wayland with this error:

kwin_scene_opengl: 0x502: GL_INVALID_OPERATION error generated.

The actual alt-tab function works perfectly fine, it’s just the log is spammed by this.
I tested the different modes of alt-tab, all of them caused this issue except for “Compact”

My plasma renderer settings are
Rendering Backend: open GL
Render Loop: automatic
GL Core Profile Force: false

System specs are:
OS: Arch
Display server: wayland
Kernel: 6.11.5-zen1-1-zen
Plasma/kwin version 6.2.2
GPU gtx 1070, nvidia-dkms 560.35.03

Are there any known fixes? Or any ideas what i can try to resolve the issue or at least stop the error being spammed?

I am having the exact same error with alt tabbing.

System Specs:
OS: Arch (CachyOS)
Display: Wayland
Kernel: 6.12.6-2-cachyos
Plasma Version: 6.2.4
GPU: RTX 3060
GPU Driver: 565.77

It doesn’t cause any problems, but out of curiosity did you ever end up fixing the issue?

It’s a harmless console error, but it’s caused by minor issues with the GPU drivers. You can ignore it.

Would be nice if this could be suppressed in some form, the minor GPU errors can be quite noisy when trying to read journald ^^’

Hi - Not a solution for the core GPU driver issue, but if you know that you’re not looking for anything related to kwin_wayland when looking through the journal, you could use journalctl --exclude-identifier=kwin_wayland to filter that out from the view.
