Problem combining standard shader with image effects on ios 8

Hi everyone,

I'd like to apply image effects on my camera and then run the scene on an iPad Air 2 (ios 8.1.2). The standard shader (with fade option) and image effects work fine separately on the device. Unfortunately I can't apply image effects if there are some transparent materials in my scene (such as big windows). Only transparent objects moves on the camera and the others freeze ... Also the screen tears and is partially blue.

I've been looking for someone who had the same problem for the last 2 days but never found a fix...

Thanks for your time !
