Video Hidden in Fullscreen IE11
This is a pretty obscure problem and unfortunately I can't provide an example to test with, but here is my problem:
I have a JWPlayer that is embedded in an iframe. I have a custom progress bar and custom video controls for this player, so I made a custom fullscreen method using the fullscreen API that allows the controls and progress bar to go fullscreen as well. In Chrome and Firefox this all works as expected, but in IE11, the player displays as only a black screen (it plays as expected when not in fullscreen mode). I looked into the CSS for the player and for some reason the "jwvideo" class has "visibility: hidden" in the CSS, and the controls are reenabled (the controls were disabled using the setControls(false) function). When I remove the "visibility: hidden" CSS, the video shows up. Why do you think this is happening?
