Screenshots:
- overflowing before scrolling (with menu arrows): http://twitpic.com/4mx21y
- overflowing after scrolling: http://twitpic.com/4mx2ca -- sorry, got this
one a little quickly
In Natty in my current setup, the menu is just barely long enough to
overflow if I add this USB wifi device I found. That's why I'm able to
scroll a bit and remove the scroll arrows to show the full menu.
FWIW, I was able to reproduce this on Maverick; setting the laptop
display to 800x600 so it's small enough to not fit the menu, with
another, larger display above; the gnome-panel is on the primary,
800x600 display. The menu tries to overflow to the top display due to
the bottom one being too small, but somehow doesn't draw on the top
display; you only see the drop shadow over the panel.
In this case however, I think it's that GTK itself is calculating screen
sizes to attempt to show the menu where it fits, but is either not able
to display above (not over) gnome-panel due to limitations, or actually
gets painted off-screen.
Rolf, can you please confirm whether 3D effects are enabled on your
system, since it could be an issue with compiz drawing stuff on the
screen. I don't think it is, as it's more likely to be something at the
GTK level, but let's be sure.
I'm reassigning this to GTK and we should definitely open a bug about
this upstream, in GNOME.
As for nm-applet, I really don't think it's an issue with it, since
there are no changes to menu drawing processes in the patches we carry.
It's a simple enough GtkMenu, it just has quite a lot of items.
