Unity panel revealed when in Evince full screen mode

[Ingo Gerth]

Binary package hint: overlay-scrollbar

Steps to reproduce:
* Open a PDF in Evince
* Maximize the file by pressing F11
* Move mouse cursor to scrollbar in top right corner

What should happen:
* The grip should appear to move the scrollbar

What happens instead:
* The grip does indeed appear and works
* However, the unity panel also pops up in a translucent fashion and overlays the program. It won't disappear until you exit and reopen the full screen mode again. The panel is even usable!

I can confirm this bug. But unlike mentioned by Ingo in the bug description, clicking on the grippy makes the panel disappear again. The panel only comes in the timeframe between the appearance of the grippy and the click on the grippy. The rest is normal.

BTW, maybe the difference between my experience and Ingo's is because my panel is set to be opaque, while Ingo's seems to be set to be translucent in CCSM?

[Ingo Gerth (igerth)]

Maybe, indeed I have set it to 50% transparency.

I don't know how I could fix this... try bugging unity

[Andrea Cimitan (cimi)]

after a small chat with sam, it looks like this is a stacking bug in compiz, and should be fixed with the release coming

[Andrea Cimitan (cimi)]

FYI (didrocks) this bug is related to the restacking done on the map event of the thumb. Sam is aware of that and told me there could be an issue in compiz.

[Sam Spilsbury (smspillaz)]

Right, its more of a general issue with how we handle windows that map after fullscreen windows above them. Turns out that panels are somehow going on top of the fullscreen window in any case. Try it with this

1) unload unity
2) launch gnome-panel
3) fullscreen evince
4) switch to vt and run DISPLAY=:0 someapp
5) switch back, and notice that the panels are now on top.

I'll endeavour to fix it soon

I can't reproduce this anymore, so sam has fixed this
