Screen shot of incorrect rendering

https://domenicobrz.github.io/webgl/projects/SSRefractionDepthPeeling/ renders incorrectly on an iPhone 15 Pro Max running iOS 17.4.1. It renders correctly on desktop Safari on Apple Silicon.

Could this be related to GPU register pressure, and failure to compile certain shaders? I don't have a DevTools debugging environment set up for this configuration.
