If I remember correctly that used to be possible in an ancient Houdini version, but sadly enough for some reason they removed that feature.

You can however with the modeler plugin, it has a "SubD Isolines" feature that does just that. You can use it only for previewing though, not while modeling.

If you do a lot of modeling in Houdini, Modeler for Houdini is really worth checking out, it will speed up the workflow a lot and makes modeling in Houdini less frustrating.

did you try setting the 3D Viewports to OpenGL instead of the fancy new buggy Vulkan in the Prefs ?

I had some similar tumbling issues in H21 and this seems to have fixed it for me.

Maybe it’s related to this issue : https://www.sidefx.com/forum/topic/102061/ [www.sidefx.com]
