System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: Radeon (TM) RX 470 Graphics ATI Technologies Inc. 4.5.13587 Core Profile Context 20.3.1 26.20.15029.15007

Blender Version
Broken: version: 2.83 (sub 13), branch: master, commit date: 2020-04-11 15:16, hash: 85de07e64c
Worked: 2.82

Short description of error
If a mesh has open edges (eg. default plane), corners between those edges will get rounded after the first subdivision level.

This seems like a the same issue as #74869 that still persists for open edges.

Exact steps for others to reproduce the error
Create a plane
Add Multires modifier
Switch to simple
Subdivide 2+ times

Yes I can confirm.
It seems like the multires has some shrinkage problems, as seen here too: #75631

Of course.
What you mean?
You need to set it as confirmed bug.

I thought you wanted to close it as duplicate. Which seems wrong as in #75631, 2.7x is the reported working version.

You need to set it as confirmed bug.

if you (and OP, being familiar with the discussion in #74869 ) say so. I don't know much here.
