Ubuntu 12.04 gnome classic panel displayed on full screen videos

Bug Description

On Ubuntu 12.04 gnome classic, the gnome panel will always display when playing videos on full screen mode.

Steps to reproduce:
  At login prompt change to gnome classic.
  Open a browser, go to youtube.com and select a video.
  Click the 'Full Screen' button to maximize.
  Gnome panel should disappear, instead it's still displayed.

Attached screenshot.

Edit: It behaves like this even when playing videos locally with a media player such as vlc. The gnome panel initially disappears but reappears after a couple of seconds.

As a workaround before playing any videos on full screen, set the gnome panel to hidden. It will still show a 1px white border though.

I can reproduce this, with a little difference, though - the video starts in fullscreen just fine, but after some time (might be a minute or half an hour, don't know what causes it) the panels (I am using two - at the top and and the bottom) pop up.

I have reproduced this problem with the Gnome Classic desktop

In fullscreen mode this occurs on the change of minute and seems to be caused by the clock applet.

However, when viewing in windowed mode, any action on the desktop e.g. clicking on the Application menu, passing the mouse over the window list or clicking a button to take the screenshot will cause vlc to expand its window vertically to fit the screen

I hope this is of some assistance.

The behaviour is also affected by the "Place windows" ability of Compiz.
If you turn this feature off (by CCSM), the problem doesn't occur, but all new windows are placed at 0,0 coordinates (I'm not using any other WM, besides Compiz).

same here had all these probs, had thought it was all being caused by the place windows applet in compiz (which worked fine in 10.10) interesting about the clock if that has to do with anything.

I use gnome-panel with 12.04LTS.

When using fullscreen Adobe Flash player I see the top menubar plus the bottom starus bar, plus I get some strange pointer behaviour (cannot reach the bottom part of the screen) when I use XBMC mediacenter.

However, all these problems went away when I logged in using "Gnome Classic (no effects)" instead of "Gnome Classic".

I am using ATI Radeom HD 4250 with the proprietary driver.

that does stop the window placement/panels in full screen problems but it makes my windows look ugly, and turns off things I use a lot like the ring switcher compiz plugin, which is worse. for me anyway

Can confirm that for me it was caused by the clock on the top pager updating while using the place compiz plugin, for now have removed the clock (<special>+<alt>+rightclick remove from panel), that's stopped it popping up. I think the problem is with place plugin though and there's a bug report here https://bugs.launchpad.net/compiz-core/+bug/976032.

As for the turns-out-to-be-unrelated windows moving themselves about/jumping to the top of the screen thing that I was having that was caused by wobbly windows plugin which has a snap feature by default set to <shift> changed to <disabled> to stop.

Same Problem if i want to watch falsh videos in Fullscreen, also if you auto-hide the bottom panel it seems that the falsh video is a bit out of screen. Didnt make any changes, got a Radeon HD 4800 propitary Driver.

i can reproduce this in two ways:
* the digits of Minutes or seconds in the clock aplet change
* the system draws lines on the system monitor applet

I have the same problem with youtube fullscreen as well as vlc and totem.
After half a minute or so the unity top and side panel pops up.
very annoying.

I'm running 12.04 with unity.

turns out removing the clock applet didn't solve, it's there again. drat

I can reproduce here also:
- Youtube fullscreen always has both top and bottom bars.
- Totem DVD fullscreen will initially have bars, but after 5-10 minutes the bars will appear over the fullscreenness. Turning off/on fullscreen hides them again for another 5-10 minutes (repeat until end of film).

Gnome Classic (no effects) seems absolutely fine, only the effectfull version is affected.

If it helps in any way, I came to the conclusion that the "Place windows" plugin is called even for windows that are already on the screen, and not only for windows that are new, and that it changes the position and size of the windows, so that the remain on the screen and not overlap the panels.

I think I have the same problem. Whether it's a Flash video or wine application, anything that tries to use fullscreen mode has the top and bottom gnome panels showing and covering up the application/video. Am using Gnome3 with effects.

This bug causes fullscreen mode to be almost useless for me. Whether it's the clock, window list, or workspace pager, my panel comes back almost instantly after I trigger fullscreen mode

I can replicate problem with any youtube video playing at anytime.
Compizconfig has an option to disable 'place window' and it works like a charm. Haven't notice any other change.

I would like to know if somebody has found a solution to this or at least if the problem is with gnome-panel or the compiz plugin. Disabling the plugin is not possible to me since I really need it, I'm using it to place some applications in place along a dual monitor after login. Thanks people!
