Hi Oli, Comparing ChimeraX trackpad pinch zoom to Chimera I observed that ChimeraX exhibits more rotational jitter. I've reduced the jitter by reducing the ChimeraX trackpad twist speed from 6 to 2. When you place two fingers on the trackpad and move them in a circle about the midpoint between the fingers this twist produces a rotation of the model about an axis perpendicular to the screen. A 90 degree finger twist was producing about a 450 degree rotation in ChimeraX while in Chimera it produces only 180 degree rotation. More details here: https://www.rbvi.ucsf.edu/trac/ChimeraX/ticket/9623 You can adjust the twist speed in your current ChimeraX using menu ChimeraX / Settings, Trackpad tab, Trackpad Twist Speed option. If you want the most stable zoom you can even set that to 1 or 0 so that twist is minimized or eliminated. Tom

Hi Oli,
I agree pinch zoom in ChimeraX on a Mac trackpad always does some rotation too. It may be in Chimera it better separated pinch zoom from two finger rotation. I'll investigate.
Did you know that 4-finger drag up or down on a Mac trackpad in ChimeraX does a zoom?

Hi,
The trackpad zoom/rotation settings in ChimeraX seem very different from “old” Chimera. Is there any way to replicate the behavior from Chimera?
Specifically, when I pinch to zoom in ChimeraX, I often find the view rotating a lot, unless I am very careful, which does not happen in Chimera. I have tried playing around with the trackpad twist sensitivity, but so far have been unable to find settings similar to the default in Chimera.
