Isocurve view bug

Hi,

The isocurve display options seems buggy.
See this video: https://nc.on-situ.com/s/p9SSbLXqqPjeyA6

  • When isocurve density is set to 0, the isocurve display stay like density=1
  • When density=0 and you uncheck “show surface isocurve”, the isocurve stay visible, but when density>=1 and you uncheck “show surface isocurve”, then isocurves disappear.
  • The isocurve density can go under 0 (but reset to 0 after a second).

File with the polysurface attached.
