Quickly mousing between menu's is chopy and graphically unappealing

[Britt Yazel]

Quickly mousing between drop down menu's on the Global menu and between the drop down indicators is glitchy and graphically unappealing. There is not a smooth transition between the menu's and it leaves a lot to be desired.

To reference Mac OS X, they're global menu is very smooth when mousing between the menus. Also, Applications such as LibreOffice seem to have a 'better' response when quickly mousing between menu's, but it still needs work.

that has been the case since compiz unity's inception. Probably won't get fixed anytime soon :/

Too bad Unity is built on top of Compiz :-/ Not to be a downer, but Compiz definitely seems to be a weak link. The benefits of Compiz are the desktop effects, most of which are not enabled by default. Too bad Unity couldn't follow in Gnome-Shell/Cinamon's footsteps by creating a javascript-style shell, and just cut out Compiz entirely.
