Short description of error
Only on the Shader Editor.
When you zoom in using the MacBook trackpad it zooms randomly, not following the cursor. This is different than the behaviour on the 3D Viewport.
Exact steps for others to reproduce the error
Zoom in on the Shader Editor. It zooms differently than the 3D Viewport, which zooms to the mouse cursor location.
