Comment 9 for bug 731790

Jean-Baptiste, thank you for looking into this. I can confirm that I experienced both cases 1 and 3 as you put in comment #7.

I had case 1 with Evince, Libreoffice, Nautilus, and Gedit, and it seems like it doesn't matter what the application is.

I had case 3 with Evince, Libreoffice and Mathematica. Till your post I hadn't thought they were related. But both cases are triggered by clicks on the Launcher icons, and clicks don't have to be too many or too quick.

I can easily say that both cases become more probable as the Unity session uptime gets longer. I had reported another bug where long uptimes causes the Launcher not to hide or dodge. Might be related if there is some kind of degradation in Launcher (or Compiz?) as time goes (I'm not a developer, but I'm sure you can put this vague sentence into context).

I'm not sure what you mean by case 2. When it happens, window decorations are still there but the top panel and Launcher are gone? I don't think I had that one then...
