Issues with standard Glass/Stained BumpDistort on iOS

Unity Engine
1

  1. On the device (4S) the FX/Glass/Stained BumpDistort works only when an Image Effect is turned on. Otherwise it turns black (like as it got no texture from the grab pass)

  2. Sometimes but not always it even “disables” the Full Screen Image Effect (which then has no visible effect on the device anymore)

Is this a bug, my stupidity or normal behavior?

I had a similar problem, I fixed it by turning on “32bit display buffer”… or “24 bit depth buffer” (can’t remember exactly which solved my problem).
Maybe you can check that.

Thanks! Will try that.
