panel superposition

[PIGEON Alexandre]

Hi, I just installed unity on my computer and I had some issue with the launcher but when I change the opacity of the panel, I notice that there was 2 panel runing at the same time (see attached picture : we can see that the menu of the active application is displayed twice).
thanks, Alex.

I've experienced this once, but when using Evolution. Setting as confirmed.

I can confirm it is a duplicate of my bug.

Is there a way to kill the second one?

[GreyWar (greywar-asdf)]

This still happening with nvidia twinview (mode: clones). My Unity package is up to date ( 3.8.6-0ubuntu1).

[liamdawe (liamdawe)]

Issue has been fixed for me on ati 5770 :)

[Alfred Rossi (alfredr)]

I think this bug still happens for me as it does for GreyWar in comment #8. To reproduce enable a second display with nvidia twinview and set the position to "clones".
