On D54250WYK NUC model the issue cannot be reproduced.
This is not actually a regression since you are testing newer hardware relative to what was released at the time of this release. I did some further testing with the 3.19 kernel which has support for the newer HD 6000 Graphics device and it works correctly for genericx86-64, so a workaround would be to use 3.19 as the PREFERRED_VERSION for 1.8.1. or to use the meta-intel intel-corei7-64 MACHINE type. Since we don't upgrade the kernel version (we might update the srcrev, but not the version) during a dot.dot, this will not be fixed.
As per last comment set it as verified won't fix.
