Display messed up... Display drivers crashed?

[Mike Morell]

I have been using Parallels 9 for quite some time and love it, but when I started it up today it looks as though the screen is really crappy in terms of color and resolution. the toolbars which are semi-transparent red are either black or pure white. I cannot enter coherence mode either.
