Can confirm whenever multires is used and smooth() is involved (Smooth Brush, Mask Smooth) -- cannot reproduce using anything else...

Will do some investigations [9a1ed28365, 3e86bb2d0b or 8e8952b7e3 might be involved?]

quoting @brecht from D3807:

Sergey is working on this, once the new subsurf/multires code is enabled by default it will be solved. So not worth trying to fix now.

So this is a known limitation (and will be fixed shortly), so archiving for now (we can always reopen if issues remain after work on multires sculpting is finished)
