WindowServer crashing in El Capitan

I'm getting a WindowServer crash to Login Screen every so often when Mac is in active use (this does not seem to be happening when it's idle).

My console Log is telling me that it's somewhere in the NVidia GL Driver from what I gather, but I'm not a kernel debugger.

Is there anyone more familiar with this error?

OS Version

10.11.1 Beta (15B30a)

Hardware

Mac Pro (Early 2009)

2.66 GHz Quad-Core Intel Xeon

7 GB 1066 MHz DDR3 ECC (strange, I know, but it's been rock solid until El Capitan)

NVIDIA GeForce GTX 760 2048 MB

It *might* be a Mission Control setting with this Display Driver configuration.

I've turned off "Displays have separate spaces" and the system so far *SEEMS* to be more stable.

I'll keep you posted over the course of the weekend.

Apparently it's an issue with 2009 Mac Pros + dual monitors: https://discussions.apple.com/thread/7252069

I've had to run just one monitor for the last couple weeks 😕

Your post about changing setting in Mission Control helped me. See my post on page 4:

Thanks a lot!

turning off "Displays have separate spaces" decreases my WindowServer CPU usage from 30~80% down to under 10% immediately. Thanks!!!
