Bug Description

I haven't yet figured out how to make it happen. But generally if I full-screen evince (in particular, but also other apps), sometimes the panel and titlebar come back and stay, obscuring part of the window. If I then un-fullscreen and re-fullscreen, they hide again.

Panel doesn't autohide still existing in Unity 3.8.10-0ubuntu2 on updated Natty. (Upgrade from Maverick).
No multimonitor involved like in Bug #734908, happens on single monitor here too.
Happens also with single monitor and libreoffice Bug #764253.
Specially anoying when watching fullscreen video.
Please make the panel autohide, at least for videos.

Again, the most trivial, 100% reproducible way for me to do this is to start up evince, full-screen it, hit 'ctrl-alt-t' to start an xterm. After that, evince will have the top and left panels over it.

But this is while xterm is on top of evince right? In that case, it is
not a bug, see http://standards.freedesktop.org/wm-spec/wm-spec-latest.html#STACKINGORDER

It is not mentioned explicitly in that specification, however, the
implicit rule is that panels and always-on-top windows must always go
above normal windows, and a normal window can be raised above a
fullscreen window temporarily, so when that happens the panels need to
go on top of the normal window (and hence on top of the fullscreen
window too)

No. It stays that way forevermore.

I can't reproduce this bug using the 2011-05-27 steps (comment 14) with unity 4.8.2-0ubuntu4. Instead I have the opposite problem: after pressing Ctrl Alt T, the menu bar for the Terminal window is not available until I focus another window (such as the Evince window) and then refocus the terminal window.
