Comment # 5 on bug 96906 from Jolan Luff

I haven't tested with anything newer than 16.30.x yet. (I use Arch Linux and
the unofficial package hasn't been updated)

I didn't see any mention of OpenCL fixes in the changelog so I haven't tried to
update myself.  I did just check and it looks like 16.50.X may be coming soon. 
Will report back if no one else beats me to it.
