FacebookGameroom Windows Game started with Window Size 100x200

Hello, When i starting my game from FB Gameroom it's looks like very low-res, but when made some research i found that my game: Screen.height and Screen.width are 100x200, but resolution is OK. Sometimes my window size is broken from start![alt text][1] Does somebody know how to fix it?

Here is my Resolution settings [1]: /storage/temp/86715-12312.png
