System Information
Operating system: Linux-6.1.0-1008-oem-x86_64-with-glibc2.35 64 Bits
Graphics card: NVIDIA GeForce RTX 3060/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 525.105.17

Blender Version
Broken: version: 3.5.1, branch: blender-v3.5-release, commit date: 2023-04-24 18:11, hash: e1ccd9d4a1d3
Worked: (newest version of Blender that worked as expected)

Short description of error

The boundary of a non manifold mesh stops moving in Sculpt Mode.

Exact steps for others to reproduce the error

Select the mesh, enter the Sculpt Mode and try to move the boundary of the mesh with the Grab brush, vertices on the boundary seems to be locked on position. Any new mesh (non manifold) added or create in the file will have the same issue with the boundary.

Copy and paste the mesh into a new blender scene and the boundary of the mesh will move again.

Attached video showing what's happening.

Hi, thanks for the report. Not a bug, this is an effect of Mesh boundary property.
Disable it and see if that solves the issue.

Hey, I met you at last Blender Conference!

Oh sorry I didn't know about this menu, this is the same option on the Brush menu on the image?
Because on the Brush menu it's not activated, but it seems to do the same thing.

Is there any shortcut that activate this option?
Because I'm sure that I didn't enter the Auto-Masking menu to enable it.

Yes, same auto-masking properties are added to multiple panels (I'm not sure why)
@JulienKaspar , maybe you've an idea about this?

Maybe you changed the property value accidently from auto-masking pie menu: Alt-A

I met you at last Blender Conference!

I remember, yes :)

Nice and thank you for the support.

A would only point that if it's the same option I think it should be enable/disable on both menus. I've check only on the Brush menu for the Mesh Boundary option and it was disable, that's why I thought it was a bug, but it seems to be a feature. :D

To clarify: This is not the exact same option. The auto-masking options in the brush settings are only for the active brush. So the settings can vary from brush to brush.
This is useful when a brush is created for a more specific behavior.

The scene auto-masking settings are the primary ones that should be used via the pie menu on Alt A.
