I think it's the hidden "Embed" and "URL" and windows trying to update.
To stop the flickering, click the up arrow in the lower right corner of the video control toolbar, select the bottom option to shrink the video and show the Embed and URL windows. Flickering stops. I think those windows are doing something like a periodic "set_visible(true)" call which shouldn't have an effect when the video is playing in normal mode, but screws up the display anyway. -- Flickering on sites with Flash video + Flash buttons https://bugs.launchpad.net/bugs/484976 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
