The bug description, shader files, screenshots, platform details, and reproduction instructions, are all available in this GitHub issue:

The "recipient" shader is supposed to render a space scene, but instead gives a red image. In the "variant" shader, we add `+ 0.0` to an expression (which should have no effect) and the image is now black.
Paul - I can confirm that the correct image is being rendered on our current Adreno 420 drivers with both fragment shaders..
The HTC One M7 has an older Adreno 320 GPU. The only device I have available for verification w/Adreno 320 is a Nexus 4 and can confirm the red and black results as described in https://github.com/mc-imperial/shader-compiler-bugs/issues/27
Thanks for the reply.
Can you advise of devices that we could use to test your latest drivers?
There are some links to follow here to get a list of devices with the corresponding chipset.

We checked on an Android N build.
