--- Comment #5 from Jolan Luff jolan@jolan.org --- 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.
