Fullscreen turns one of my two screens black. The left half of the fullscreen flash-app is shown on the right side of this screen.

I'm not sure what kind of information would be needed for this bug to get some progress, but as I said in my last comment, this bug appears to affect both Firefox and Opera but it also seems to affect Konqueror. I've also noticed same kind of behavior on other flash players than youtube's, like the ones engadget and vimeo use. However some other flash players, like the ones at google videos and, seem to have fullscreen working properly. My current conclusion is that the problem is probably with the way the flash player is showing content in fullscreen since some flash-video-players work properly in fullscreen and others don't.

I've also attached a series of screenshots about how the youtube player behaves on my system when using twinview.

I'm a novice with launchpad hence I won't try updating any of the bug's information and was hoping someone else would do it.

When I m using 2 graphic cards and 3 screens, I connect 2 screens to Twinview and the 3. as second XServer. The Twinview "fake Xinerama" has problems than. When I m playing a youtube video, my twinview screens turn black and I see the left half of the video in fullscreen on the right half of the right twinview screen. Some days ago I realized OpenOffice Impress presentations behave similar in fullscreen.

I found a way to solve the issue.
Step1. Open the youtube video you wanna play.
Step2. Popout the player by right clicking and choosing popout
Step3. Maximize the popout window in the desired screen (Don't use youtube player's fullscreen button)
Step4. Press F11 to put the browser to fullscreen mode.


Hope this helps you guys while a real solution is implemented.
