I think the issue with Bezier curves wasn't solved completely : in the following video for example the points don't update after changing the threshold setting.

The threshold is not by curve, it's a general setting. If you change the settings, any curve that needs update will use the new settings, so if you created a curve with a value of 0.4 and now you have 0.6, the curve is calculated using 0.6, not 0.4.

@filedescriptor could you confirm?

@MumuMundo Yes this is by design. The curve data is kept once generated. So it does not override it if you enable again. I guess there should be a way to reset the curve data. Or make the conversion more explicit.
