I'm seeing the same thing, but I've noticed that if I shrink the window performance comes back. I'm seeing slowdowns everywhere; typing, goto anything, dragging selections, scrolling, etc.
Window size appears to have a sweet spot based on total pixel area. When dragging a window edge, I can pretty much see when ST will work well, when the motion of the edge itself gets choppy everything else slows down too.
