gajim no access to hamburger menu in conversation window as it pops back
After setting up gajim and open a conversation, the conversation pops up in a new window. This conversation window has a "Hamburger menu" at the lower right corner. I can click on it to pop up, but when I try to select an entry of it, e.g. Information or History, it just flips back, and nothing happens.
The same behaviour occurs also when I try to activate OMEMO encryption by clicking onto the lock. It pops up, but even if I click on OMEMO, the menu just flips back and Default stays selected. Hence, I only can receive OMEMO encrypted messages, but not send any.
On mobian with Phosh I don't experience such a problem. Seems to be a general graphical problem. Anybody an idea, or can replicate that behaviour?
