Comment 65 for bug 665546

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.
