that's a duplicate I think

[Rebecca Palmer (rebecca-palmer)]

Confirmed (amd64 Natty, Ubuntu Classic (No effects) mode, Intel 965GM graphics).

It occurs fairly frequently, but I do not yet have a reproducible way to trigger it. It can occur on either the top or bottom panel, including over the menus (in which case using them clears it).

I can't find any duplicate reports of this bug, if anyone does please label as such.

[Rebecca Palmer (rebecca-palmer)]

I have now found a reliable way to trigger this bug:

1. In Firefox, open a website that uses tooltips on hyperlinks (eg. http://en.wikipedia.org/ )

2. Move the mouse over a link near the bottom of the screen, so a tooltip appears overlapping the bottom panel.

3. Move the mouse off this link; the tooltip will disappear, and the bottom bar reappear correctly.

4. Move the mouse to another link, away from the bottom; when its tooltip appears, the area of bottom bar that was previously under the *first* tooltip will change to desktop background.

Some other kinds of tooltip can also trigger this bug, including the ones used by panel items themselves, but not all kinds trigger it reliably.

Once triggered, the bug persists until the area is redrawn (eg. by using a panel item in the affected area). If only part of the area is redrawn only that part returns to normal.
