Hi Mike, Henry,

I submitted the updated version of the patch as I was experiencing this bug at
the time (at the end of 2015). I can give it another test for you this weekend
if you like, but I can't imagine how this could be resolved without this patch.

The tl;dr is that there are fears around a software patent for this technology,
which appears to be shipped on every graphics card released in the last decade,
but requires a license to implement in software. The patent in question appears
to expire in October 2017 (at which point there shouldn't be an issue with Wine
merging this into stable?)

In the meantime, the patch does serve a purpose, although it's debatable as to
whether homebrew is the right place to host it. The current recipe does make
things *very* easy to end users though.

What are your thoughts?
