Broken: version: 3.2.0, branch: master, commit date: 2022-06-08 10:22, hash:
e05e1e3691
Worked: 3.2.1
So the original issue came with

This apparently got "fixed" by

Short description of error
Cycles affected by the brushes.mp4
Rendering in the viewport is constantly restarted by some sculpting brushes and the position of mouse cursor.
1, Moving the mouse cursor out of the viewport can stop causing the problem.
2, Not all brushes are causing the problem. For example, Grab brush, Elastic brush, Draw brush, Mask brush are not causing the problem.
3, This problem does not happen in Blender 3.1 or Blender 3.0.
note: after
285a68b7bb
, it seems only the Pose & Boundary brushes are still affected (and only if you hover the mesh)Exact steps for others to reproduce the error
A sample file is included.

Thanks for the report.
I can confirm in 3.2.1 but not in 3.1 and 3.3

Exact commit is not known to me. @lichtwerk , can you check please?
Will bisect when this changed (for the better).
Note though that the Pose and Boundary brushes are still affected if you hover over the mesh (also in master)

So nothing to backport to 3.2.1 I guess
CC @JosephEagar
Note though this was entirely fine in 3.2.1 (even with the
Pose
&Boundary
brushes, which are now still broken in that regard in master), will check what was the original cause in the first place (maybe that will help fix said two brushes as well...)Added subscriber: @Jeroen-Bakker

Ok. I had to do a small amount of cleanup, but I think I've gotten this fixed. The root cause was paint-related code in
sculpt_update_object
(called by its external API,BKE_sculpt_update_object_for_edit
). I went through and renamed the two functions'needs_color
(which was actually unused) parameter tois_paint_tool
. I also fixed a bunch of places where I had named API parameters or functions "color" instead of "paint", and a few bugs caused by it.Added subscriber: @Alex_Rom
