Bug Description

Hello Debugger's,

I have a really anoying bug report to file this time.

When i use the Switcher ("ALT + TAB" ) and in that i make unity show me the application windows (by " ALT + ^ "/or just pressing the down-arrow) , the appearing window will be blank, when it was minimized before.
the content of the window will be shown again after risizing the window.
This actually sucks so much, because it just appeared in 12.04 and was not there in 11.10.

Thanks for noticing my bug.

Exactly the same problem for me since 12.04 (whereas that point was ok on 11.10).
I don't know what additionnal informations coud be usefull ...

I'm running Unity 3D on a laptop, up-to-date 12.04 installation upgraded from 11.10.
I'm encountering this problem right now with the "static application switcher" alt-tab behavior, but the problem was the same with the default unity alt-tab mechanism.
