I come across this kind of problem periodically online. Not necessarily a Studio One problem, but it almost always seems to be PC related, though. My guess is that it has to do with all the possible options you have out there for graphics cards, where a Mac is much more limited.
Have you made sure your graphic drivers are up to date, that’s solved some issues in the past. Also I think the way certain software and games can be “power managed” by the graphic card software. Try plying with different settings or just turning it off in order to troubleshoot your problem.
Another thing it might be is an OpenGL/CL thing. I’m not sure if that can be updated, but its worthwhile looking into.
