On my lower system PC, Nvidia GTX 750ti, I3 and Unity 5.4.b20 I got some strange visual glitches if SSR is attached to the cam in build only. Seems it happen only if HDR is enabled. (Linear, Deffered, HDR)

This is the old SSR, could you try with the latest one ? You can get it from the Bitbucket repository.
Okay thank you.
