KDE neon User Edition / Plasma 6.7.4
If you have a network shortcut to unavailable network address (registered as shortcut in dolphin) , and try to make a “print screen” (Spectacle) and save to this destination, Plasma will hang.
Either you need to reboot, either disconnect the computer from any network to recover.
this is after half an hour hanging, after disconnecting networks.
Yep, you’ve discovered why manually mounting network disks (typically in /etc/fstab, using ancient documentation) can be a bad idea. There’s an ongoing project to reduce the pain here, but manual network mounts will never offer an amazing experience.
Until that project has been completed, I would recommend following the documentation we have for KDE Linux: Access Network Shares - KDE Linux
If the “Known limitations” are problems for your specific use case, then instead try what’s listed at On-Demand NFS and Samba Connections in Linux with Systemd Automount - Ray Against the Machine.
It is not a mounted FS. It’s a ssh shortcut ( fish://aegir@192.168.1.87/home/aegir/ )
Aha, that certainly does invalidate what I wrote.
It would have been helpful to mention it at the beginning. 
For sure, but as a matter of fact I always use network shortcuts in dolphin for ssh shortcuts, so it didn’t even occur to me that this could be interpreted as mounted filesystems.
