Viewport; red artifacts constantly showing up

Recommended Posts

Just picked up r21 (R21.207). Waited so long, and so disappointed because I can't use it. After a few minutes, my viewports keep turning all red. It's intermittent, chaining views sometimes makes it go away, makes it change, but nothing corrects it. I've played around with my Open GL settings / memory etc. Can find not a single post anywhere about this. I can't be the only one I'm thinking. Any ideas would be appreciated immensely. Attached images of what I'm fighting...
