This problem has to do with the integration of the full-screen writing app Focuswriter within Unity. It appeared before I upgraded from Ubuntu 12.04 to 12.10 - probably caused by a an automatically upgraded change that persist in 12.10:
When I minimize Focuswriter after it has been in full-screen mode the launcher is invisible - instead of seeing it I just see a rectangle the color of my desktop background where it should have been. The launcher becomes visible if I click the area once but then I'm likely to hit an icon and unwillingly open a program.
I've reported the bug to the developer of the program here: https://github.com/gottcode/focuswriter/issues/101 He has labeled the bug "upstream" saying that the bug is can only be fixed in Unity.
My questions are:
- Does anyone (perhaps experiencing problems with other full-screen programs) have a solution or workaround so the launcher won't disappear?
- Where can I file a bug report for this problem?
Update: the problem is the same when I minimize from full-screen in LyX, LibreOffice Writer and Firefox - and probably any other program in full-screen mode.
