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
Sculpt mode + reference image + clip + brush scale -viewport overlays = flicker glitch

Exact steps for others to reproduce the error
Quite tedious setup, but confirmed with vanilla blender, can be really annoying when having references all around the place.

Create object
Place reference image behind it (empty as image)
viewport clip back half of the cube (alt+b)
disable viewport overlays
go sculpt mode
look at the cube from the (opened) back, as if through (viewport disabled) reference image
change brush size

voilá! object flickers with every brush size or strength change.

This seems to somehow refresh/enable the viewport overlays with every brush width/strength change.

Thanks for the report. Can confirm the regression, bisecting.

I can reproduce an issue where rendering doesn't work correctly under similar circumstances.
But it happens regardless of the presence of reference images and causes the mesh to disappear, not to flicker.
So I'm not 100% sure if we are looking at the exact same issue.

Could you try this build when it's ready and check if it fixes the issue for you?

Hello, OP here:

Can confirm the reference image was not connected with the issue in the first place. My bad.
And also yes, we are looking at the same issue - dissappear is a better word for that glitch.

Can confirm the issue is fixed in the branch you linked.

thank you and congrats, good job!
