maybe it's the memory leak i am suffering for months if not years
my machine has 32GB RAM and 4x3.5 Ghz which is maybe the reason "ALT+F2
and type "restart-plasma.sh" is no problem while with less memory likely
everything takes ages
after some hours or intense work switch between applications takes ages
here and when restart plasma eveyrthing becomes smooth again

I have 32G and a powerful machine as well but if I switch between users,
I cannot type anything at all. I will try the alt+F2 and see if that
I will watch memory and maybe try to restart plasma before trying to
It is time related so a memory leak may be an issue. Once I can switch
users, I can switch back and forth almost instantly. Give it time and
the time to change gets longer and longer.
I have restarted plasma in the past with the same commands as you used.
I guess this means it points more to plasmashell than sddm or Xorg.
Doing a search on plasmashell memory leak and there are many that have
created cron jobs to restart their plasmashell on a regular basis.
In my case, that may be a great idea.
I just noticed that for KDE5.10 and above they now recommend
I will start to monitor the memory usage with
top -b -n 1 |grep plasmashell
Maybe create a script to log the data as well.
Thanks. I will watch this over the next couple of days.
Also testing on a different computer.
