Just to be clear, mine is not a thing commercially known as NUC, it's
just a bare Asrock D1800B-ITX motherboard (with embedded passive cooled
Celeron J1800) in a custom mini-ITX case.

I have just tried a Fedora 24 Live USB stick, with all packages as
they were when Fedora 24 was released (kernel 4.5.5, intel driver
2.99.917) and everything worked fine out-of-the-box: youtube in Firefox,
gnomeshell, (though not my test video files, because there is no
RPMFusion). I saw no artifact at all.

However I have no idea whether I was running with SNA or UXA, it was
just working directly out-of-the-box (and I haven't found
/var/log/Xorg.0.log).

That's a very good point, one can't expect a FreeBSD driver port to fix
native bugs. Unfortunately, at least in my case, it seems the issue
stems from the port rather than the original driver.


Thanks for the comment,
