Something is wrong with navigation on my machine. Mouse movements are opposite my expectation (I guess just a preference), and the movements are so sensitive it jumps around a lot and I can't really navigate where I intend to. I'm on an iMac w/magic mouse.
Linux with a touchpad, here, and yes the movements appears to accelerate at a ridiculous rate for me. It's by far the worst navigation I've experienced on a map.
>As for the direction of the movement, think of it as pushing a globe and not moving a camera.
It's not the style of navigation that feels weird. It feels like they're doing the usual arcball but with some weird multiplier attached to rotations so it doesn't feel 1:1 but something like 1:4.
It's really obvious if you zoom out enough to see the entire globe and grab one horizon then drag it 180 degrees to the other. The globe rotates almost twice in that span instead of ~1/2 rotation.
That issue has actually been fixed. Google Haps is completely useable with a magi mouse (before, it was approximately 50x too sensitive, because of the magic mouse's higher resolution).
It's difficult to see how the magic mouse is responsible for the problems here. If I click and drag a point on a map, I expect that point to remain under the cursor. But – as described above – the map moves too fast.
It's not specific to any particular mouse. The clicked on point doesn't stay under the cursor as you drag, even slowly. There is too much easing applied after releasing the button.
I noticed that when using the touchpad on my laptop (Thinkpad E545, Slackware64-current, Firefox 50.something). The trackpoint + physical mouse buttons seems to be less sensitive, but still registers direction really weirdly.
