as i attempt to put my pen onto the canvas to draw the program will zoom out by half and then more. I'll zoom back into the program but it does it again, & sometimes will change my mouse pointer into a zoom icon, leaving it stuck in zoom

Reproducible: Always

Steps to Reproduce:
1.open krita with mac ox
2. start new file
3. approach canvas with pen

Actual Results:  
zoom out

Expected Results:  
not zoomed out

it's super annoying, the bug will sometimes keep the cursor from even going into the canvas, making the mouse disappear and crash the system.
