Weird wacom bug with Photoshop CC. Can't use the brush unless I right-click.

Hi,

I am having the weirdest bug right now. I am using an Intuos Pro M and Photoshop CC. When I try to use the brush tool instead of painting a stroke, the behavior is to drag the canvas (like when you are using the hand tool). It only happens when I am using the wacom, so for example I can paint normally using the mouse. The only way for me to draw is to configure a pen button to be right-click and only when I press and hold the right-click button on the pen does the brush draw normally.

I am going to make a listed summary of all the weird stuff that is happening.

• When using the brush or erase tool with the pen, the canvas is dragged around instead of painting strokes.
• If only happens with the wacom, the mouse works properly.
• I can paint/erase with the pen only if I press and hold right-click with the pen.
• It only happens on files after I use the zoom tool to zoom-in, that means when I open a file I can paint normally, then if I zoom in it starts behaving weirdly.
• It happens in every file.
• When the drag bug happens the Hand tool is not highlighted as selected, nor the mouse pointer changes to a hand, it just shows nothing.
• EDIT breaking news: I tried with a Bamboo and it's also happening!

Things I have already tried.

1. Deleting and reinstalling the wacom drivers (currently using version 6.3.29-6)
2. Installing an older driver (tried 6.3.29-3)
3. Reinstalling Photoshop CC without keeping user preferences.
   
   

I am attaching a gif file where you can see the behavior.

• I create a new file
• Draw normally
• Switch to the zoom tool with Z and zoom in, drawing still works
• Zoom in more
• Drawing becomes dragging, but if I press and hold right click, I can draw
