[unity-3d/oneiric] Vanishing window buttons after unmaximizing apps

[tista]

[methods]
1. open any apps from any where you want.
2. click the apps's maximize button to maximize.
3. metacity window frame were hidden and window control buttons were showed on unity panel via hover and/or any way.
4. click the "unmaximize" button on unity panel to restore the apps to unmaximize.
5. metacity window frame were shown again and this frame only shows window title without any control buttons. and also window title seems to be shifted to left a bit (the length seems exactly same as the width of control buttons?).

[recovery]
* Moving mouse pointer across over the desired area of control buttons.
* Changed focus to other apps.

[Reproducible percentages]
* especially firefox scores top-rated, around 50% or higher.
* even if on any apps were tested, usually this issue comes up via ways repeated more than 4 and/or 5 times.

Same problem here, I'm using nVidia drivers.

Is this fixed in Precise or Oneiric for you?

[Adolfo Jayme Barrientos (fitojb)]

I have not seen this any more in Precise.

Thanks for the bug report. Is that still an issue for you Ubuntu 12.04 with all updates applied? Can you please test that and let us know?
