I have the following opera version:
Version: 24.0.1558.53 - Checking for updates...
Update stream: Stable
System: Windows 7 64-bit (WoW64)
Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.94 Safari/537.36 OPR/24.0.1558.53

In this version of Opera we can preview the tab by placing the mouse over the tab.
But whenever I am watching a video on youtube and then place the mouse over the tab to preview another tab but I dont change the tab, but remain in the same in which Youtube is being played, the video on youtube become "Black" as in I can hear the sound but the video screen goes black.
To come out of this condition I need to just scroll up / down once and instantly the video is restored.
Can somebody tell me is this a bug in Opera or is it because of youtube developer tools being enable??
