Moving Flash to a new window freezes Flash display #320

Open ivazqueznet opened 8 years ago

On latest git (7ba5f2de) moving a tab containing a full window Flash to a new window causes the Flash display to freeze, although audio continues working.

I confirm that. Happens when XEmbed mode is in use (enabled by default). Adding either enable_windowed_mode = 0 or enable_xembed = 0 to the config file disables using XEmbed and therefore prevents graphics from freezing.

Not sure yet why that's happening. But found an interesting workaround. Opening a flash video in another tab fixes that which was frozen by moving to another window. Perhaps it's somehow related to the message passing to the window thread.

Hmm. Tried to do that in Opera 12, in had ability to drag tabs between windows too. Test flash movie works fine, with video visible, after such a move. So, issue could be caused by Firefox internals.
