WebGL Safari PostProcess

Hello,

I’m having a really annoying issue with the postprocess.
My customer wanted something running on web and the issue I have is that on Chrome and Firefox (and Opera) post-process are running well. But on safari they are totally missing resulting in a darker scene.

I can’t really find any information concerning this.
I found some spotlight issues, some PP pass unsupported with no vertex shader.

The other issue, is that I had the post process working on safari only one time without knowing that there could be problem with them, but never been able to get them again (and I don’t know how I did to have them working)

Nobody ?

What happens on edge? I vaguely remember post processing stack requires webgl 2.0 (can’t recall though). Edge and Safari only support webgl 1.0.

use unity 2018.4.13 and use webgl 1.0, asm.js. Everything will be solved
you may encounter audio and input errors on ios. with the above way everything is fine
