Is curve editing broken for anyone else or do I just not know how to use it?

I am using the color balance curve editor on Macos Sonoma.

Whenever I try to grab an existing point and move it, it just creates a new point right next to it. Once I create a point, there is no way I can delete it either (or at least I cannot find a way).

Am I just confused on how to use it, or is there a usability issue on Macos with trackpad?

If I remember correctly you delete a point by dragging it outside of the curve box

I’m not aware of anyone else who has had this problem. When you try to drag a point, does the new point always get created at the same location relative to the point you want to move? If so, what happens if you offset your cursor by the opposite amount before trying to grab the point?

Not on Macos here, but i have similar observations, that moving these points can be fiddling. On a 4k-monitor i see a small offset between mouse-pointer and adressed position (RT only!).
Clicking and dragging only, after the point in target has changed its color by mouseover, prevents from creating new points.

I agree with these observations.

Not using RT but ART, and I have a similar problem on my own builds on Mac. Also sometimes with sliders I have to click slightly on the side to grab the slider correctly, and the sliders often don’t refresh until I put the mouse cursor back onto the slider a second time.
