I experienced this issue today on my 12th gen i7-1260p Framework Laptop 13 running Fedora 38. I think it was triggered by the laptop waking up from suspend in my bag, failing to suspend again and getting very hot yesterday evening (draining a lot of the battery). After that, I charged it and used it for a bit before suspending it overnight. I’ve been very frustrated today trying to figure out why my laptop had gotten so slow but was able to reproduce the same behaviour using s-tui as in the OP.
I wasn’t able to fix it by restarting (I tried several times) but was able to eventually resolve it by shutting the laptop down, leaving it off for about 10-15 minutes and then turning it on again. I hope it doesn’t come back
