Comment 21 for bug 965953

It shouldn't be hard to reproduce, I noticed it immediately after upgrading. Just use the gnome classic session, add a bottom panel, and set the indicator applet on the bottom panel in Precise. The WiFi indicator is the easiest to reproduce the issue as it updates frequently. Sound indicator is another example, when it changes tracks. Try scrubbing left and right across the indicators. The patch above is a sort of fix, but it adds a new bug where frequently instead of being too small, the indicator menus become massive and reach nearly to the top of the screen. I've been living with this bug for a long time as a bottom panel user of Precise :/
