Photoshop bugs when when wacom tablet connected

Hello guys, doing this post because I got a bug on photoshop and it kinda depress me.

So, when I connect my wacom tablet to my computer, some of my photoshop's shortcuts are modified, like the zoom (usually it's used as a progressive zoom, but the bug makes him selective, it's kind of weird and not practical). 

More, every brush, when the image is zoomed as I can see the entire page, are like dotted, not constant. I have the habit to do sketches with low thickness brushes so it bothers me a lot. 

I already tried to update every pilots, to reset brushes and preferences, did some manipulations to resolve wacom's bugs but nothing change. Help me please :<
