3D SBS Subtitles Chromecast


I have a Chromecast 2.0 and I stream a 3D movie from a SMB share with Infuse 3.6 on my iPhone 6 Plus to the Chromecast 2.0. I have a external SBS subtitle in .ass format in the same folder as the movie the subtitle is not showing correctly it is out of the picture.

Is this a bug or maybe I am doing something wrong or maybe it is unsupported?
