I've noticed lockups twice now while configuring kwin under wayland, so I'm filing a bug to track. I don't have logs (please let me know where to look and I can try to find) currently.

1) Right clicked on firefox titlebar, more actions, configure special application settings, configured to remove titlebar, apply -> lockup

2) Settings, virtual desktops, added 10, apply -> lockup

In both cases, I wasn't able to alt-ctrl-del or alt-sysrq reisub; the latter seems like the kernel may have been impacted.

I haven't encountered similar lockups doing anything else, so it seems correlated with kwin configuration. 

This is Kubuntu 21.10, 4:5.22.5-0ubuntu1.

Can you clarify what you did here? You should see a combobox with available virtual desktops, but you can't add new desktops

Sorry, I don't remember. You could close this one out. I'll try again with Wayland after the next ubuntu release.
