SUMMARY

When trying to save a PDF file stored on a SMB share after modification (for example with annotations), an error occurs with a dialog box saying "Impossible to save the file in "/tmp/Okular.xxxxyyyy". Try to save it in another location".

When launching Okular from the terminal tab of Dolphin, a message states "kf.windowsystem: static int KX11Extras::currentDesktop() may only be used on X11". Hence, it is potentially an issue related to Wayland compatibility and the use of X11-specific functions.

There is no problem to save a file if it is stored locally (for instance in /home)

STEPS TO REPRODUCE
1. Open a PDF file store on a SMB share with Okular
2. Highlight some text (annotation)
3. Save the file => Error

OBSERVED RESULT

Impossible to save a modified PDF file on a SMB share if working in a Wayland session

EXPECTED RESULT

Possibility to save the file on a SMB share

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Archlinux

This is completely unrelated to this issue

Ok. Just tried to provide some context and analyze
