Were you previously zoomed in at a different spot before that zoom? If so, you’re experiencing the “curved” zoom.
Curves only happen when you’re zoomed in at a spot and then zoom in/out to a totally different spot with different x y and %, and there’s really nothing you can do about it.
The only times zooms go in a straight linear path is:
- when you’re zoomed out at default (100%) then zoom into any spot
- when you’re zoomed in at a spot then zoom to a spot with the same %
- when you’re zoomed in at a spot then zoom in/out to the same exact x and y coordinates but only change the %
