I think that this is an important patch we should discuss on this
mailing list. The patch clearly is wrong, as it is only trying to
address the result of a problem, but not the problem itself. What
happens is that after opening a submenu the interaction of the mouse has
an offset, when the window manager repositions the submenu. I think that
this is caused by the code not accepting any repositioning events for
the submenu. I would expect that the backend tries to tell gui where the
submenu window did get positioned, but as we are in a tracking loop we
ignore these events.
An easy solution would be to run the normal event loop for a short time
after we attach a new submenu, but this looks like just another hack.
Any better idea, how to resolve the issue?
