Anytime I try to draw, zoom in/out, literally anything, these black boxes pop up all over my canvas. And conveniently, they only pop up where I’m currently drawing. I’ll have a box over my sketch, and once I draw another line BOOM there’s another box over that. I can’t draw at all because of this weird glitch. I haven’t been able to draw for at least a week now.
