Rendering bug on iOS using Standard Asset Shader (Glass / Stained Bump Distort)

Hello, I’m working on a fireplace app, and I have a very nice heat effect using particles with the FX/Glass/Stained BumpDistort shader and a normal map. It is working well on Android platforms I’ve tested, but now testing tvOS I’m seeing an issue. The shader effect is applied correctly, but everywhere on screen that is NOT covered by a distortion particle is being rendered incorrectly.

Has anyone seen issue like this on ios/tvos? I think iphone has the same bug but I dont have access to the device right now to make sure.

Or any ideas how to fix it? Thanks!

I have the same issue with a shader that uses grab pass, did you find a way to fix this @callen ?
