Unity top panel restarts when changing tabs in Kile or Eclipse

[aras]

When I switch tabs in Kile (tex editing application) or the Eclipse IDE the application menu shows up brifly pushing things down, right after that the unity panels on top disapears for a brief moment and then immediately starts again. This causes the screen to resize quickly to fill in the empty space after the panel is gone and then resize again when the panel comes pack to claim its space again. The whole thing happens in under one second, and after its done things are back to normal. However, this looks like a glich visually and it also makes switching tabs (which unfortunately is something I have to do a lot of) a bit and slow and not very pleasing to the eye.

My guess is that this issue is related to HUD since just before it happens the application menu (File Edit ...) shows up in the top.

Here is how to reproduce the bug in ubuntu 12.04 with Unity:
 - Open Kile
 - Open two or more documents inside Kile
 - Use the mouse to switch from one document tab to another one
 - You will see the top panel disapear and reapear quickly

Let me know if I can provide any other information to help debug this issue.
