We used a custom-written OpenGL launcher (pre-compiled binaries available for download at [1]). [2] contains a fragment shader which yields the expected image ("original.frag") and a fragment shader which produces the incorrect output ("variant.frag"). Note that the difference between the two shaders is very similar to a bug observed on Windows 10, on a R9 Fury device (already reported via this form and available at [3]).
Command-line usage:
$ ./get-image variant.frag --persist
