I was tearing my hair out over this, too. I came across a post in this forum--which I can no longer find--where one of the posters reported that if the MC window was "restored down" (the middle button between "Minimize" and "Close,") then "Maximized," that the situation with the "Display Driver Error" message corrected itself.
(This is assuming your system has been working properly, but just hiccups on this message once in a while.)
It has worked for me several times now. I don't understand it. (Hey, sooner or later there had to be something, right?

This really points up one of the wondrous things about tech forums, and also that you should always try the least-dangerous suggestion first.
It also bolsters the old adage that, "Computers are dumber than humans but smarter than programmers."
Hats off to the tinkerer that found this. If it's you, speak up to receive your due.
