Window dragging on Unity breaks window borders when dragging across desktops in workspace view.

[Mark East]

When dragging windows from one desktop (workspace) to another in my 11.10 install it seems to break the window bar across the top. It can also fail to highlight the desktop I am dragging it to properly. To replicate open any application (e.g. firefox), press alt+s and drag the window to another desktop. If you drag from the bottom right up through the middle you will see the whole bar disappear and the destination desktop doesn't light up.

Please see the screenshots for more information.

Would help if I attached the screenshots :)

Oh and when I mean it fails to highlight the destination desktop I actually mean it does highlight it with a border but doesn't illuminate it like it should.

Second screenshot attached.
