SUMMARY STEPS TO REPRODUCE 1. connect to remote fs (sshfs host: folder) 2. open folder in dolphin with preview enabled and tree view (to increase the effect) 3. open dolphin, and experience 20s interface freeze on every action once doplhin interacts with remote fs OBSERVED RESULT Looks like loading (thumbnails?) keeps freezing whole dolphin It's very bad experience to wait sometimes over 20s to go back to different directory or trying to select files to do something with them. EXPECTED RESULT never freeze interface, and just load thumbnails and file details slowly SOFTWARE/OS VERSIONS Linux/KDE Plasma: plasmashell 5.22.5 (available in About System) KDE Plasma Version: 5.22.5 KDE Frameworks Version: 5.85.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION I know that doing async task is hard and prone to problems, but it's very bad experience. Same behavior happen if I have hard drive in sleep state, and I open dolphin. Dolphin doesn't even show for the whole thime hard drive spinup (i hear it very clearly as It's external usb drive and it takes at least 7s) and it doesn't matter if I want to use it, as long as It's mounted and shown in dolphin, doplhin trying to get drive usage and that is waking up hard drive.
Same thing on neon unstable when I open a sshfs share created by KDE Connect with Dolphin. Operating System: KDE neon Unstable Edition KDE Plasma Version: 5.23.80 KDE Frameworks Version: 5.89.0 Qt Version: 5.15.3 Graphics Platform: Wayland
Similar scenario here, I think my scenario may just be a little easier to reproduce. On boot I mount a network drive locally, however when I switched routers the ip range changed, rendering it unavailable. This caused dolphin to be very slow in use, and the effect is very similar to what has been described here. And probably a lot easier to reproduce. Of course also much easier to fix. Below, an anonymized version of my fstab line: NETWORKUSER@192.168.11.11:/storage/share /home/USERNAME/NETWORKDRIVE fuse.sshfs noauto,x-systemd.automount,_netdev,user,idmap=user,follow_symlinks,identityfile=/home/USERNAME/.ssh/id_rsa,allow_other,default_permissions,uid=1000,gid=1000 0 0 Adapting this line to your own setup, while making sure the target cannot be reached, should reproduce it. Possibly just having garbage data here could also work, I have not tested if the folder still gets mounted if you do.

Can confirm this issue. Linux: Manjaro KDE KDE Plasma Version: 5.22.5 KDE Frameworks Version: 5.95.0 Qt Version: 5.15.2 Kernel Version: 5.17.15-1-MANJARO x64
Can confirm. Even worse, Dolphin does not respect the (default) setting of not loading thumbnails for remote filesystems. So not only does it terribly suck at loading (please compare to Windows + SMB), it's impossible to stop it from doing it making Dolphin unsuitable for work with remote filesystems. Linux: Arch Linux KDE Plasma Version: 5.25.5-1 KDE Frameworks Version: 5.98.0-1 Qt Version: 5.15.6+kde+r177-1 Kernel Version: 5.19.13-arch1-1
I can also confirm. Not only thumbnails but reading basic metadata information of remote files also freezes up Dolphin. Dolphin expects all metadata of files to be loaded immediately, but this fails for remote filesystems.
Same problem here mounting a Samba with CIFS on Dolphin 22.12.0, Plasma 5.26.4, Fedora 37. The bug is even worse for me as it completely freezes the whole desktop. Nothing responds anymore. I can't even switch to a terminal using ctrl+alt+Fx to kill the process. I have to hard shutdown the system every time.
I also have this problem and it is very annoying.
Same here, with smb.
