I got one fix tho, but it will make you unable to do other stuff in photpshop. So wont really call it a fix... just a ... "for now thing" aka how Adobe fix it,quick.
If you go under performance and check off the Graphic processer, it will stop the freezing. But it will be laggier, not smooth at all, lines will become rather pixelated when you zoom out and you will be unable to rotate the canvas.
If this "My old tablet was the Intuos pro medium model PTH-651" is the reason im gonna flip a table.
