Desktop environment freezes in Linux xfce when opening save file dialog window

[yds12]

When I click the save button, the system file dialog opens, but then it is frozen: I cannot click on the button to save or cancel, and all my desktop UI becomes unresponsive to mouse action. I can still do ALT+TAB and the keyboard works, so killing the process via terminal can unfreeze the desktop.

I'm on Linux with xfce desktop.

Other than this so far everything works nicely, great work!

I can confirm that this happens on Kubuntu (KDE) 20.04 LTS as well.
