OK, so it's been a while since I've played around with Chief's raytrace utility, probably a couple of years.  I don't really need it for the majority of the work I do.  Just last night I swapped my i5 6500 processor for an i7 7700k 4.2 ghz processor, and wanted to watch chief raytrace with blazing speed.  Well, it did, but it was all purple.  What gives?  I don't even know where to start on this problem...  I've tried many files and they all do this.   Has anyone seen this before?
