Comment 46 for bug 275285

I was able to reproduce this yesterday on an intel 965 laptop. And also confirm comment #19 - moving a window to the foreground makes the video start playing again. This seems to be a fairly new issue, like within the past couple weeks; however the last code change to -intel was Sept 20, so it must be something other than -intel. Looking over xorg-server for the past couple weeks, there's been quite a few code changes but none that leap out as obvious issues that would affect flash video playback.

Could someone try booting an older kernel and see if you can reproduce it there? If it can't be reproduced, then we may want to look into recent kernel changes for Ubuntu.
