Description of problem:
If I set YouTube to serve HTML5 video, and then watch a video fullscreen, a flickering black rectangle appears at the bottom of the screen, after the YouTube video controls slide away.

Version-Release number of selected component (if applicable):
xorg-x11-drv-nouveau-0.0.16-27.20110720gitb806e3f.fc16.x86_64

How reproducible:
Always

Steps to Reproduce:
0. Start Firefox
1. Set YouTube to serve HTML5 (specifically, WebM): http://www.youtube.com/html5
2. Go to http://www.youtube.com/watch?v=kz6dw_BIdNA&list=FLj889r3mEHSdq-IJPbtHQnA&index=4&feature=plpp_video
3. Click the fullscreen button
4. Click play again if necessary.
5. Wait for the YouTube buttons at the bottom of the fullscreen to slide away (they do so after a few seconds)

No flicker

Additional info:

Comment 1 Robin Green 2011-12-03 17:06:44 UTC
Note that HTML5 "full screen" is not actually full screen.

Can't see this bug when playing the video URL using mplayer, so it may be an application-level bug. However, because mplayer really does play it fullscreen (with -vo xv or -vo gl, anyway) it shows up as a letterbox so there is a black band below it which would hide the flicker, if there was a flicker.

Anyway, using mplayer is a workaround.

Comment 2 Fedora End Of Life 2013-01-16 12:28:31 UTC
This message is a reminder that Fedora 16 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 16. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '16'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 16's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 16 is end of life. If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora, you are encouraged to click on 
"Clone This Bug" and open it against that version of Fedora.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:

Comment 3 Fedora End Of Life 2013-02-13 12:45:08 UTC
Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
