Weird green pixels in main window

I have one user that’s having issues anytime she tries anything in Rhino. Others in the office have opened the file and don’t have the same problem. It must be a setting somewhere. She recently updated her graphics card driver so I’m not sure it’s that. I can always check again for another update.

Any ideas?

Hello - can you please have the user run the SystemInfo command in Rhino, and post the results? I suspect a plug-in may be getting its oar in here.
