Yep, fair enough. See here: Making sure you're not a bot!
Next set of kernel releases should fix it, if you’re feeling adventurous you can also apply this patch downstream: Making sure you're not a bot!
Still surprised it made it into an LTS kernel; I’ve been seeing these issues too, but only when on gmeet calls, my WM doesn’t seem to tax the GPU as much as plasma, so probably just hits the issue less often.
