Hi guys, been having a problem for a week now in fedora 43.

After half an hour of light use, my kde keyboard starts crashing at regular intervals, the taskbar is unresponsive, and the shutdown greeter will crash if i try to restart or shut down. I have to power cycle the system to turn it off, not the best.

Looking for anyone also experiencing the problem has not yielded any hits, so I'm posting here ๐Ÿ˜…

Thus far i have tried: -Restarting -Disabling Firefox video decoding (closest fix i could find in searches) -Rolling back to my previous Friday backups

The issue persists ๐Ÿ˜“

I don't know enough about Linux to troubleshoot the problem effectively ๐Ÿ˜…

Sounds like a memory leak to me. To test my theory you could open a memory monitor on your first clean boot (from Terminal you could use the "top" tool). Sort by memory consumption in top. Then note what the largest consumers of RAM are. Check again after about 10 min, and then another 10 min later. Do you see a process that is increasing that you wouldn't expect to be?

    I thought the same thing, but couldn't find anything new or unexpected in sysmon ๐Ÿ˜“

    Sat at low cpu and gpu usage.

    Run a memory test, I was having issues like this that turned out to be some RAM that passed self-tests but failed during certain kinds of writes.
