Same issue. Just updated to the latest version yesterday and it feels so unstable...or at least very clunky. (64 bit, 1TB hard drive, 16GB ram 3+Ghz quadcore, so doubtful if the machine is struggling with a 1080p psd with 2 layers). I agree totally with hansolocambo​ using a Wacom tablet is and has been for years (since about CS1) an absolute nightmare with Photoshop. I've lost count how many times I've had to uninstall, reinstall, update (repeat ad-nauseam) 'wacom' drivers when Adobe release an update. I'm pretty convinced Adobe believe Wacom are a myth as there seems to be little if any communication or beta testing between the two. And yea Adobe I'm looking at you...another company's drivers aren't the issue when the issue only shows its face when YOU release an updated version of YOUR software. There are always work arounds but it would be nice (as a paying customer) if.....just once, updating CC didn't involve revisiting and troubleshooting a list of pre-existing problems and work-arounds, all for the sake of a few features which serve little purpose than to massage your virtual ego....while removing or changing features that your users rely on. And on that note if you go to Select > (press shift while selecting) Select and Mask you'll be able to access the old refine edge dialogue, which is immeasurable superior to the new Select and Mask effort (I'm calling it an effort because, well, it is...its a piece of steaming beige dog sh*te) that doesn't seem capable of getting close to the results of the old Refine Edge options. Ok, my apologies, rant over and blood pressure returning to normal.....until i need to use the lasso tool again
