Created attachment 469616 [details] screenshot Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0b5pre) Gecko/20100826 Minefield/4.0b5pre If you have "Tabs on Top" selected under OS X and drag tabs to a new position, the drop indicator is cut-off on top because of the title bar. It's an OS X issue only.
Same problem on Linux. Indicators are drawn if either tabs-on-top is deactivated (awesomebar is above the tab-bar) or menubar is visible above tab bar.
