I am using Emacs 25.3.2 on Linux Ubuntu 16.04.
The problem is that several of the menu bar items produce empty drop-downs. A grey box appears, but with nothing inside. It looks like this:
I originally noticed this happening for the
Virtual Envs and after playing around a lot with various modes, saving, closing, restarting Emacs and so on, I believe it is always specific to the current mode. The
Buffers tabs never seem to have a problem.
Pressing F10 seems to reset something and then everything works again, but after some time (I haven't been able to determine when/why exactly), the mode-relevant menu bar tabs seems to once again be empty.
Any clues as to what might be causing this?
I have seen this problem, but it appears to have been version specific and also a different issue to mine.
