Description of the problem
Using
three.jsresults in shaders unable to compile (sometimes). It got this bug while using the starter code from https://github.com/expo/expo-threeHowever, I know that it is not a React Native, or Expo or Expo-Three bug because I was able to get the code to work perfectly on an iPad (Apple A9 GPU -- GLES 3.0). However it did not work on a Xiaomi RedMi 4A (Adreno 308 -- GLES 3.0 -- Android 6) nor did it work on an older Android phone running Android Jellybean.
The error log printed out two long .vert and .frag source codes and I tried to find out which files it was from and I saw that the source files were assembled from chunks, so I didn't know how to find out where it was assembled.
You can edit for small-test.
