System Information
Operating system: Windows-10-10.0.19045-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3060/PCIe/SSE2 NVIDIA Corporation 4.6.0 NVIDIA 546.17

Blender Version
Broken: version: 4.0.0, branch: blender-v4.0-release, commit date: 2023-11-13 17:26, hash: 878f71061b8e
Worked: (newest version of Blender that worked as expected)

Short description of error
Seems like a viewport error, visible only in sculpt mode but actually is visible both in workbench and in material preview mode.

Exact steps for others to reproduce the error
Unfortunately I was not able to reproduce, I tried multires on remeshed Suzanne it does look ok.

My file with error contains vertex groups, UV maps, shapekeys, non-quads, sharp edges, etc. I suspect the issue might come from there.

I guess the error could be determinable by the looks of the glitch.

Note: the glitch is dynamic - does not look the same on the same polygons, but it shifts-changes every sculpt click, even one the parts which were untouched by the sculpt action (this leads me to the conclusion its not gemetry but rather viewport error).
Note: it is not caused by viewport shading settings (I tried disabling shadow,cavity, changing matcap)
Note: the glitch look changes everytime the multires "display modifier in viewport" is disabled and re-enabled

Reminder - the glitch is only visible in sculpt mode.
