Comment on attachment 420203 [details] Patch I could make things go awry with this patch. start playing a video (not YouTube), go to full screen. Now put the video in PiP and press the X button in the top right corner. The video would exit PiP mode and go back to non-full screen but the video has now disappeared. Tapping play can only allow you to hear the video, but you can't see anything
