Can't see Unity 4.3 sprite layer behind Refraction object

I'm writing a platformer using new Unity 4.3 workflow. So, I made a background and player as unity sprites. The player is animated sprite. Then, I put a plate with standard refraction material between camera and my sprites, to make visual distortion... lets say it's a glass wall. And... I couldn't see it. Then I changed camera projection mode to Perspective and I was able to see how my glass wall distorts the background. Good. However, the player sprite is on the same Z position as background but on other sorting layer and when the player goes behind the glass plate - it disappears. But normally I can see it. That's weird. So, the glass wall works just with the background but not with the player. Is it a bug or I'm doing anything wrong?
