Bug Description

Binary package hint: unity-2d

Following updates today (9th April 2011), any attempt to open Audacity in Unity-2D causes the desktop environment to crash, leaving just the Audacity window visible with no borders. I've tried with global menus enabled and disabled in audacity.desktop.

Just confirmed that, on the same machine, Unity runs Audacity OK. Logged out, logged back into Unity and ran Audacity fine.

(The reason I'm running 2D at all BTW, is that I have other problems with the desktop locking up and white windows but it managed to hold itself together long enough to run Audacity).

Have the same problem running Synaptic. Consistently crashing the desktop.

I've just noticed that it may not be a crash and more of a repainting issue. If I hit Super-S a few times the launcher and top "panel" come back again.

Richard, could you please attach to this bug report the file ~/.xsession-errors ?

Logged out and back in. All I started was a terminal to follow the output of .xsession-errors.

I then hit the Super key to bring up the dash (had to hit it twice) and launched Audacity. Launcher and top panel/global menu disappeared when Audacity window appeared. No window decoration on Audacity window. Hit Super-S a couple of times and the launcher and panel came back.

Closed Audacity and made a copy of .xsession-errors (attached).

OK, I have a better pattern of failure now:

I lose launcher and panel in these cases:

1. Hit Super to open the Dash and escape to cancel
2. Hit Super to open the Dash and click on an active window without entering text
3. Hit Super to open the Dash and run an application that opens full-screen (Audacity/Synaptic in my case)
4. Hit Super to open the Dash, click on a lens, e.g. applications, then escape to cancel

It behaves correctly in these cases:

1. Hit Super to open the Dash and Super again to cancel
2. Hit Super to open the Dash and click on the desktop to cancel

It recovers if I Hit Super-S a couple of times.

I confirm this is due to the patch introduced to fix bug 750753 .
The fix wasn't tested with the metacity compositor running, which displays this issue.
Regular metacity doesn't have this problem, so as a workaround you can disable the compositor until a proper fix is released.
