Splines bevel size

Hi Friends!
Something terrible with splines in blender. In 3ds max splines works perfect. Is it possible to make splines bevel size constant how it was made in 3ds max?

Maxs splines:

upd. In 2D splines works perfect but complex shapes in 3D are bad.

Yes, I can confirm the same issue here with Blender 2.81a and 2.82

Is it a regression? Meaning did it work as expected in previous versions? If so it might make sense to submit it in a bug report.
