There is a dark line that appears under the Toolbar and under the Quick Access search area next to Perspectives. This seems to be some kind of display issue in
Eclipse Juno. I am running
Ubuntu 12.10. The version of
Eclipse that I originally installed was a part of the ADT (Android Developer Tools) Bundle
Unfortunately it is difficult to see these lines in the screenshot since the image is really zoomed out. In order to clearly see this, press Ctrl-Plus to zoom in on the screenshot in a browser window.
If I hide the Toolbar then the dark line does not appear.
