When I start SteamVR and set up, everything look great and tracking work great and my phone screen look like this: http://i.imgur.com/yOmx0el.png
But when I try to start game or tutorial, everything is mess up and not look right on phone screen like this: http://i.imgur.com/G4vv1nR.png
If move phone around, square on right will change different shade of color and stuff but nothing happen on left side of screen. I not know why this happen. I play other PC game before and use TriDef to make 3D and work great. But when try to use SteamVR to play actual VR game I have this problems.
Problem is specific to SteamVR.
When I open Display Mirror in SteamVR on my PC, it look like this: http://i.imgur.com/cLG8ZT1.png

And when I open Display Mirror, suddenly this shape appear on left side of phone screen and is constant flash on and off: http://i.imgur.com/17HmsnK.png
