Voice-of-Shadow Spinebot's answer is quite adequate, so there's not much I can add. There's no option to adjust the number of curve segments in the Spine project or the curve as a whole, so adding keys as you do is the correct way to do it.
在进行小偏移时、这种采样会导致这段直线曲线所影响的图片变换被放大。最后导致非常不和谐的卡顿。
Could you show us this problem visually, perhaps with an example using simple graphical images? The fact that the line segments are displayed on the curve is not a bug, but if you are experiencing severe jitter, there may be a bug or something we should fix, so I would like to confirm the specific problem you are experiencing.
