I ask th= at question because I also own a NUC (the pentium one, with the same graphi= cs) and I saw the very same artifacts you=E2=80=99re talking about with Fed= ora 23 and 24. If you boot the Fedora 24 live media, you are likely to see = them too. On Fedora 23, they only appear post install. I=E2=80=99m mentionning this here because as far as I know, the FreeBSD int= el driver is ported from Linux, and I=E2=80=99m afraid that those issues we= re also ported with it. On the Linux side, those artifacts made the computer unusable. One way to g= et rid of them was to disable SNA acceleration in xorg.conf. This change ha= s a cost, though, as it dramatically slows down the graphical rendering. An= other one was to switch from Xorg to Wayland, which seems unaffected by the= bug, probably because it does not use the same acceleration preset. Interestingly, I never saw those artifacts with OpenSUSE Leap 42.1. It seem= s they were not widely discussed: I did not find any reference to them on G= oogle. I hope this helps a little, Marin.
