Yep, the remaining issue seems to be these shader functions:
    dFdx()
    dFdy()
    fwidth()
which are from GL_OES_standard_derivatives, that is not implemented by all drivers/platforms.

That shader code is not in Mir BTW. This bug no longer has anything to do with Mir since the first issue was separated into bug 1458689.

We need a fallback (or to avoid uncommon extensions) for the sake of portability.
