Scroll in image with only one finger in touch devices causes rubberbanding

[Quanos-Matti]

When i use only one finger on some touch devices to "scroll" in the image, the image snaps back in a rubberbanding way. When i use two fingers on those devices, everything works fine.
Device with no problems: Sony Smartphone ,Android 12, Chrome Browser Version 131.0.6778.81
Device with rubberbanding: Samsung Galaxy Tab, Android 10, Chrome Browser Version 129.0.6668.100

dragConfirm option may be interesting to prevent unintended scrolling on page main axis when panning the panorama:

But the default is false and that is described as the right option for panning with one finger, or do i get anything wrong?

[strarsis]

You are correct. It should work either way, just with one or two fingers, depending on the option.

The rubberbanding shouldn't ever happen, and there's nothing in Pannellum that I can think of that could cause it. And it obviously isn't Chrome, since you don't see it on your other device (and I've never seen it with Chrome on Android either).

My guess is that Samsung is doing something silly with the touch input prior to passing it to Chrome. I found a thread that suggests that there's an "adaptive" motion smoothing setting that might cause this: https://us.community.samsung.com/t5/Galaxy-S21/Scrolling-issue-with-Chrome/td-p/1698753
