System Information
Operating system: Linux-5.11.0-43-generic-x86_64-with-glibc2.31 64 Bits
Graphics card: NVIDIA GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 470.82.01

Blender Version
Broken: version: 3.1.0 Alpha, branch: master, commit date: 2021-12-28 08:36, hash: e28222966b
Worked: (newest version of Blender that worked as expected)

Short description of error
The origin of the object its on the red line, however im using an empty as mirror object to offset the mirror center,thats the green line.
in edit mode this works fine but in sculpt mode using the grab brush it doesn't really know where the clipping plane should be so it produces those artifacs on the red line.

Exact steps for others to reproduce the error

mirror clipping sculpt.blend
Use sculpt brush grab and drag left to right in the blue circle, do this with clipping disable and enable in the mirror modifier

Can confirm, it is not taking the mirror_ob into account in sculpt mode.
Would be worth to check edbm_do_smooth_vertex_execas well [which also does not seem to take this into account]
