WebGL on Safari: troubles with some post-processing

Unity Engine

Safari issues with post-processings:

  • ColorGrading: screen is black, only 2D interface is visible; and Safari Javascript Console displays following error: “TextureFormat 17 not supported”
  • Grain gives some parasite flickering at screen borders (old movies’ style)
  • AntiAlias, AmbientOcclusion, Bloom and DepthOfField work fine (i didn’t test the others)

These issues happen only with Safari. works fine on Firefox.

perhaps Firefox is using WebGL2.0. You can check that in the browser console. If that’s the case, you can try to disable webgl2, just go to about:config and look for webgl.enable-webgl2
