DrawMeshWires Working, DrawSubDWires Not Working?

(8.1.23325.13001, 2023-11-21)

For the attached script, I expect both the SubD and the Mesh to have red wireframes.

Summary:
e.Display.DrawMeshWires(bar2, System.Drawing.Color.Red, 3);
seems to be working while
e.Display.DrawSubDWires(bar, System.Drawing.Color.Red, 3);
doesn’t.

The code is being executed and doesn’t raise an exception (see console prints and results on command line).

Am I missing something? I think I had this working before.

pipeline-fail.cs (1.7 KB)
systeminfo.txt (2.5 KB)

(this is repro steps, I originally ran into the problem in compiled code)

thanks for reporting,
I can confirm this isn’t working here either
