Comment 1 Nate Graham 2021-03-09 02:00:27 UTC 
How many virtual desktops do you have? And is this reproducible in Plasma 5.21?
Comment 2 Patrick Silva 2021-03-13 12:33:18 UTC 
I can't reproduce this plasmashell crash on Arch (Plasma 5.21.2) or neon unstable. I use 4 virtual desktops on both systems.
Comment 3 Nate Graham 2021-03-13 14:21:17 UTC 
I've been using virtual desktops more and I can't reproduce it either. Let's call it fixed.
