As I don't know much about systems I typed "dmesg" and what fell into my eyes are the following messages:
[ 1561.359808] perf: interrupt took too long (2502 > 2500), lowering kernel.perf_event_max_sample_rate to 79750
FWIW, I have been seeing those for a while, at least since 42.3. I looked them up once, it is something about the kernel reducing some data sampling to not impact the system.
If you use 'dmesg -T', you'll also see the timestamp - they might not be recent messages.
Now it happens every few minutes. I can't work. I've uploaded var/log/messages for today: https://www.daniel-bauer.com/div/messages1.txt
Try another desktop.
Apart of QT errors I see that there are "snapper" and "baloo" messages, although I have nothing btrf on my system and have turned off search in KDE system settings. This also seems strange to me.
But the indexer may be running. Try "balooctl status" in a terminal, then "balooctl disable". I suspect that the btrfs "features" may need system time now and then and impact performance.
Please ask me for any information my system can give you to find out what happens here. At the moment I can't really use the system - only during writing this text I had two freezes...
I see a lot of messages from kactivitymanagerd. I don't know what that does. Open a terminal with two tabs. In one run "top -d 3.333", and in another "sudo /usr/sbin/iotop -o -d 3.3333" (maybe you have to install it). Top looks at processes, while iotop looks at disk usage. Then you can see if something is busy. -- Cheers / Saludos, Carlos E. R. (from oS Leap 15.0 x86_64 (Minas Tirith))
