Once I start up an existing file, there's no problem at all when trying to paint something. Pressure sensitivity and everything else works like a charm.
The problem starts as soon as I decide to zoom in and use the brush tool, which does no longer work. Or well... it doesn't work like it's supposed to. Instead of drawing lines, it moves the canvas. Same story with every other tool.
It's like everytime I try to make a stroke, the click of the pen registers as a click + spacebar. Which isn't possible.
The strange thing is, that this issue seems to be fixed, as long as I press right-click whilst trying to paint. Also, this issue only applies to my tablet, not the mouse. But painting with a mouse is not exactly the best solution.
So I'm pretty sure this problem is connected to my tablet, a Wacom Cintiq Pro 16, and it's drivers [?]. But maybe there's some incredibly easy solution to it all concerning Photoshop.
As a sidenote: I already de- and reinstalled Photoshop, which changed absolutely nothing.
