Short description of error

When zooming 3D View by dragging with Ctrl-MMB (or Ctrl + trackpad scroll), the zoom speed depends on the cursor position.

The "Preferences" > "Navigation" > "Zoom to Mouse Position" is disabled by default.
Disabling the "Zoom to Mouse Position" option in the keymap makes the speed consistent.

Exact steps for others to reproduce the error

With the factory default preferences.

Place the cursor at the top of the 3D View, zoom by dragging up/down with Ctrl-MMB, the speed will be high.
Place the cursor at the bottom of the 3D View, zoom by dragging with Ctrl-MMB, speed is slow.

Change the Zoom Axis setting to Horizontal, now left/right mouse movement near the left edge of the 3D View produces low zooming, and near the right edge zoom speed is high.


original report

Short description of error
Zoom axis should just set the direction to move the mouse to zoom the view. It also seems to set the zoom speed of the trackpad pinch zoom based on where the cursor is in the 3D view (eg when set to vertical, zoom is faster at the top of the view). This does not affect mousewheel zooming or 2D views. It happens whether zoom to mouse position is on or off.

Disabling this option in the keymap makes the speed consistent, but unfortunately also breaks the "Zoom to Mouse Position" option in the navigation preferences:

Exact steps for others to reproduce the error
Set zoom axis to horizontal and try zooming with trackpad pinch with cursor on both the left or right side of 3D viewport.
Set zoom axis to vertical and try zooming with trackpad pinch with cursor on either the bottom or top of the 3D viewport.

Attached video is of trackpad pinch-zooming with default settings:

Just a note that this is still an issue despite fixes having been submitted.

@PratikPB2123 - I've updated the report, it doesn't seem to be Mac specific, check again.

@jenkm , indeed. Can confirm on Windows. Wrong zoom factor in negative axis?
