Window manager cannot handle iconifying a full-screen window

[Brandon Lewis]

This bug only exists on Ubuntu 12.04 for Unity with hardware acceleration enabled. It does not reproduce on 12.10 or with Unity 2D.

I am attaching a python script which should manifest the bug. The script runs for a few seconds, displaying a window on opening. After 2 seconds, the window is placed into full-screen mode. After 4 seconds, the window is iconified. After 8 seconds, the script exits.

What you expect to see is that the window disappears and then the script exits. Instead, what usually happens is that the window vanishes briefly, along with the unity menu bar, then the window re-appears fullscreen. On occasion, the window remains hidden, but so does the menu bar.

Adding script which demonstrates the bug.

Thank you for your bug report. That ticket is quite old and we didn't get recent report of the problem, also it seems to work correctly now, closing. Feel free to reopen if you can still reproduce in more recent versions
