Hello Mali driver devs,
It appears the GLSL 3.0 compiler doesn't support GL_OES_EGL_image_external extension, required by Android 3.0+ for use with SurfaceTexture. Recompilation for #version 100 instead of #version 300 es resolves the issue. GL_OES_EGL_image_external is present in the extension strings.

Hi Pete,
Makes sense. Indeed ES3 is not meant to be backwards compatible with ES2/1.1 extensions.
Easy workaround for most, so no problem. Only caveat is that the resulting fragment shader compiled under #version 100 can only be linked with a vertex shader of the same GLSL #version.
Best,
