I don't know how to reproduce this.

This is the video link (I couldn't upload it as a file, because it is too big).

For some reason, it stopped happening. I didn't even reboot. I just used it normally.

Nvm. It started lagging again. Now, when I start a program it takes some time to show the window.

Is there anything using excessive CPU time?

CPU time or CPU usage ?
If you are talking about CPU usage, then there wasn't anything suspicious.

Weird.

Are you getting anything like this in the journal?

I can't reproduce it. To be honest, I don't know how it even happened (how to trigger it). I will make sure to make a log if I encounter it again.

I had the same issue, solved it by re-installing inxi package
