[Bug 665546] Re: Drop and sub menus don't always show up

 

Disabling animations in Compiz does not fix this.  I think we are
getting false solutions because it is easy to be fooled into thinking
that the problem is fixed because of the behavior of the problem.  I'm
pretty sure that the problem is masked due to some sort of caching of
the popup menus (disk access, graphic, who knows?).  It may appear
random simply because of flushing of whatever is being cached.

I've got wine installed which has lots and lots of sub menus under the
applications menu.  Clicking on Applications and then hovering the mouse
into the deep wine sub menus I was able to determine that the first time
I hovered over a popup it never appeared.  If I moved away from that
menu and then came back it always appeared on the second try.  Exiting
out of the applications menu and starting over shows that previously
visited popup menus showed on the first visit but any previously
unvisited popup does not appear until the second visit.

However that being said I rarely logout and I'm fairly certain that this
problem reappears from time to time on some menus (making it appear
random -- I thought it was until today).  So that is why I'm pretty sure
that something is being cached and flushed.

I'm running 10.10 with the ATI proprietary driver.
