Rendering on iPhone SE 2nd Ed. broken (upstream)

[caroparo]

Also tested on v2023.6; rendered results are broken for the test project. Using latest runtime, built with Xcode 15.1. Target device is iPhone SE 2nd generation, with iOS 16.1.2.

Attached is the result on iOS:

And the expected result rendered on PC:

Upstream issue somewhere. I'm using a lot of varyings for the fragment shader which is likely part of the story.

However, Clean Shapes is not in active development and I will not be addressing this issue in the immediate future.

Thanks a lot for the reply! There's indeed this error in XCode's Run/Console logs:

Error linking program:
ERROR: Implementation limit of 32 varying components exceeded. Unable to allocate 'v_vCircleInnerColour'.

I was able to remove varyings and distance functions for shapes I don't intend to use in my project, and render correctly.

Great! Very likely possible to reduce the register count in the general case by reusing varyings but I leave that as an exercise to the reader.
