Dear bug tracker,
The bug appeared after the following commit in indicator-appmenu:
<http://
Attached is a patch against the latest revision that narrows down the issue.
Developers more familiar with lyx or indicator-appmenu might be able to tell whether the commit exposes an earlier bug of LyX (for instance forgetting to register some signal), or whether the bug is in indicator-appmenu (in that case feel free to adapt my patch).
In particular, by looking at the comments in the source, I am not sure that the path taken to update the menu, before this commit, was at all intended. Also, symptoms of this bug include the fact that there is a small delay before the menu is updated, and Scott Kostyshak mentioned that the callback Menu::updateView() in lyx was in fact called twice. This hints at a deeper bug either in lyx or indicator-appmenu. It would be nice to solve all at once because it has made lyx feel sluggish ever since indicator-appmenu was introduced in Ubuntu.
Thanks!
In the meanwhile, the proper workaround is to run lyx with the command line:
QT_X11_
or equivalently to adapt /usr/share/
Exec=env QT_X11_
