This has nothing to do with the NUC, simply replace your desktop compositor with "compton", mate's default compositor (Marco) doesn't work correctly with any Intel gpu.
Wrong forum FYI.

From my end, I just want to let you know that Intel does not test and validate Intel® NUC on Linux; however, we know that other customers have successfully installed it. So, at this stage Intel suggests you check your Linux distro's website and forums at; Ubuntu Forums for more feedback regarding this matter.
TMASHP, thanks for the help.
