Illustrator is not frozen but you can't see anything you're doing to your work
Since the update I have had a lot of issues when creating art. Everything starts smoothly, I can see everything I'm doing in real time and can see which brush strokes I'm creating. A little ways through drawing, I can no longer see my brush strokes. I can click other options in illustrator (i.e. select layers, lock and unlock, hover over options etc.) and do other things in the process but I can't see anything that i'm actually doing to my artwork! I have to restart the program almost every ten minutes and it's driving me absolutely mad. Is there a solution for this? Is this happening to anyone else?
