Menus not working correctly with Wayland KDE

[Rogern]

Zoom 5.11.10 and 5.11.9. In a meeting using KDE on Wayland right click menus appear at random places on the screen and clicking outside the menu does not cause it to close, though using the Esc key does. Also clicking on the shield icon at the top left of the meeting only produces the dialogue for a brief flash and it then disappears.

It all works correctly  though if I run Zoom with XDG_CURRENT_DESKTOP set to GNOME.
