Expected behaviour

Selecting ”open main dialog” from the client menu brings up the main dialog.

Actual behaviour

Selecting ”open main dialog” from the client menu either does not bring up the main dialog, or brings it up only to have it disappear almost immediately. The location of the main dialog, when it does pop up, also seems random: sometimes it pops up in the top left corner of the scereen, sometimes at the center of the screen, sometimes right where the tray menu is.

If I’m quick enough to bring the mouse cursor over the main dialog when it pops up, the window seems to stay, until I take the cursor out of it, at which point the window disappears.

The settings window does still open as normal when selected, and works without issues.

Steps to reproduce

1. Select ”open main dialog” from the client (”tray”) menu

Client configuration
