John Morris, to clarify, you upgraded the OS whose hardware is the NUC5i5RYB (not some other computer with different parts) and this is reproducible?
To advise, it's much easier to deal with different hardware that has similar/same symptoms if you filed a new report with Ubuntu by ensuring you have the package xdiagnose installed, and that you click the Yes button for attaching additional debugging information running the following from a terminal: ubuntu-bug xorg Also, please feel free to subscribe me to it.
