Menu Bar unreachable

I have a problem with the menu bar of my application. When I start the ignition vision the menu bar is unreachable. I cannot click on an item and no drop-down menu is shown. As soon as I click on a tab to open a window or make it go full screen, the menu bar works again.

My app used to work fine to some moment, from which on the behavior change to the above mentioned. Unfortunately I have no idea what triggered this.

Any idea what would that be?

I am on Ignition 7.8


Sometimes no text is displayed on the menu bar.
This menu bar “freeze” also happens when I switch to another user.
Other things work. It’s just the menu bar.

Any insight to this would be highly appreciated.
