Description Mahbod Karamoozian 2024-04-11 10:44:37 UTC 
This bug happens with every libreoffice application (calc,impress,writer,etc.)
If you open the file dialouge it will cause the current session to be unresponsive

Steps:
Open a new session (for example writer)
Use the open button or ctrl+O (no need to open a file you can just close the dialouge too)

Expected results: The file should open normally if you have opened something and everything must be responsive and if you cancelled the dialouge libreoffice should be back to working just fine.
Observed results: Libreoffice freezes. You still can interact with libreoffice but any graphical feedback is absent.

Meanwhile if you use libreoffice-still it works fine which means this is a regression.

Additional notes:
DE: KDE plasma (files are opened with kdialog)
Distro: Arch Linux
Graphics: AMD Radeon Stoney Integrated Graphics
Comment 1 Mahbod Karamoozian 2024-04-11 10:50:36 UTC 
Edit: libreoffice-still works fine because it is using the builtin file dialouge and not kdialog. enabling builtin file dialouge fixes the problem in the fresh version. It seems this bug has something to do with external file dialogs.

This must be KDE6-specific.
