"Growl-like" indicator bubble clips outside the workspace area

I am using the Gnome3-classic desktop environment, and I have noticed a minor bug on my compter. The first time the "indicator bubble" (that looks like the Growl indicator bubbles on Mac) in the top right corner (after logging in), it clips outside the workspace. About 80% of the bubble is visible, and the rest is outside the workspace. The indicator bubble doesn't always clip outside, but when it contains a relatively long text notification, it does.

I am attaching an image showing the effect (with my username and the contents of the bubble grayed out).
