648535 - Youtube video visible if another window opened

Status: RESOLVED INCOMPLETE

(Firefox :: General, defect)

Description

[Swati Deshpande]

User-Agent:       Mozilla/5.0 (Windows NT 5.1; rv:2.0) Gecko/20100101 Firefox/4.0
Build Identifier: Firefox/4.0

In firefox 4, if we are playing a youtube video, then the video is visible in another open window. 

Pre-requisites: Firefox 4 opened with another window, say notepad.

Reproducible: Sometimes

Steps to Reproduce:
1. Open any youtube video.
2. After some time (1-2 minutes), open notepad window. 
Actual Results:  
The youtube video is visible on top left corner of notepad.

Expected Results:  
The video should not be playing in any other windows.

The bug is not re-producible each time. Sometimes when we open any other window after the video starts playing, the video is visible. But, in some cases, you may need to switch between firefox and notepad 3-4 times.

Is your Issue reproducible when you disable the Hardware Acceleration and restart Firefox?
If yes, please post the Content of the Graphics Section you can get via "about:support" after you re-enabled Hardware Acceleration.

Flash update does not help. 

I am not sure exactly which driver should I update because I am using FF4 on my office PC. Can you please give me exact link. Please let me know about how update will affect my PC.

I have updated FF to version 5 and I am able to re-produce it on this version as well.
