Interesting, I'm on the same hardware, even the same ram amount, but I build from source instead of chaotic aur. I know a lockup can happen if you try to use wallpapers with HDR, #250 for reference, and I don't think there is a fix for it. I would recommend checking your wallpaper library for HDR wallpapers. If that isn't the issue you could try cleaning the shader cache ~/.cache/wescene-renderer and restarting to remove any possible corrupted shaders.

No none of my wallpapers are HDR. Achtually I tried that same wallpaper from the issue https://steamcommunity.com/sharedfiles/filedetails/?id=2826681794 and couldn't even repoduce the crash on my system. The wallpaper just shows as white but my system continues functioning correctly

this is probably the same issue I been having for a while ever since KDE 5.25. Though before it would just crash kde not my whole system (i know my whole system crashed because sysrq keys don't work (i have them enabled) and journal does not log anything after the point my system becomes unresponsive also I can't ssh into my system. Only thing I can do is pull the power plug.

so that tells me that somehow it's locking up the kernel

Have you tried a different kernel? It could be a kernel setting I know tkg has a lot of edits to it. The zen kernel and arch kernel work.

They may have fixed the kernel freeze issue for HDR in mesa, I will check when I get back to my main machine.
