Fedora KDE becomes suddenly slow

Framework Laptop 13 Linux
1

Hi! My UI suddenly became very slow during usage, this reset when I rebooted. This is the second time this happened, the first was a few days ago. I managed to open system monitor and see that neither my CPU nor my GPU usage was high (in fact, very low). Also no process seemed suspicious from a first glance. I didn’t check for RAM, but I doubt that’s a problem, as I only had a few Firefox tabs open, Thunderbird and PyCharm, and I have 32GB.
Any ideas where to start looking when this happens the next time?

Which Linux distro are you using?
Fedora (was using GNOME, until I installed KDE and uninstalled all GNOME packages. This was months ago, the symptom started showing a few days ago.)

Which release version?
(if rolling release without a release version, skip this question)
Fedora 40

(If rolling release, last date updated?)
now.

Which kernel are you using?
6.10.11-200.fc40.x86_64 (64-bit)

Which BIOS version are you using?
3.05

Which Framework Laptop 13 model are you using? (AMD Ryzen™ 7040 Series, Intel® Core™ Ultra Series 1, 13th Gen Intel® Core™ , 12th Gen Intel® Core™, 11th Gen Intel® Core™)
AMD Ryzen™ 7840

I currently have this problem. System is incredibly sluggish and slow to react on mouse movement or key presses. Low CPU and memory usage.

Framework 16
Fedora 40, Kernel 6.10.11-200.fc40.x86_64
KDE Plasma 6.1.5
AMD Ryzen 7 7840HS

Just had the same thing happening on arch linux, 6.11.1-arch1-1.
No memory pressure, no temperature issues, low cpu usage.
Everything started lagging quite hard and waiting didn’t improve it. A reboot fixed it.

A reboot fixed it here as well, but it just occurred again here three days after…

I have the same issue. The UI starts lagging, waiting doesn’t fix it, nothing strange in system monitor, restarting fixes it.
AMD Ryzen 7 7840U
Fedora 40
KDE Plasma 6.2.0
Kernel 6.10.12-200.fc40.x86_64

Anything notable in syslog?

I couldn’t find anything in journalctl, except a message complaining about the system lagging.

On another note, one of the updates must have fixed it, because I’ve had days with multiple UI lags, but it’s completely gone (for now, will update if that changes).

I don’t know which update did it, but I’m on the latest fedora updates.
