Latest version (6.0), intel graphics:
1. open libreoffice presenter
2. double click on the presenter edit view
-> you can see that the panel and launcher becomes transparent
There is no crash and if you get the cursor back to the libreoffice *menu* area, the panel/launcher reappears.
See the beginning of this video (panel will disappear). As you can see, it doesn't on each double click for selecting the content, but on most of them.

i recognized the same behavior (on quantal, all updates installed) without any libreoffice app opened. the launcher gets transparent when i scrolled in emacs.
