@leocg it plays about 5 seconds and then stops for 5 seconds and continues that way. The video and audio don't seem to get out of sync, but it only happens when I'm not watching it, because im looking at a different fullscreen window. I can browse other tabs and have it play normally. Just seems to happen when I have any other fullscreen programs open, and opera is not the top window. I might be able to make a video of it if you want.
