System Information
Operating system: Windows-10-10.0.19045-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3090/PCIe/SSE2 NVIDIA Corporation 4.6.0 NVIDIA 551.23

Blender Version
Broken: version: 4.0.2, branch: blender-v4.0-release, commit date: 2023-12-05 07:41, hash: 9be62e85b727
Worked: (newest version of Blender that worked as expected)

Short description of error
I'm sculpting a heightmap in the Z-plane on a large object (12km across) but relatively low-poly. However, doing this while zoomed in (using a 3D Connexion Space Mouse) often glitches out Blender and seemingly apples the brush to everything you see in the screen.

I was zoomed into the green area sculpting away at that mountain and suddenly the entire landscape pops a bit closer to me and zooming out, I see the effect that's marked as the red dashed lines.

Exact steps for others to reproduce the error

Open the attached .blend
Use the clay strips brush on 1.0 strength in z-plane mode while zoomed in very close to the map and sculpt away.

You can see the effect in the attached file:

@RobertS hi, does this persist in 4.1 as well?: https://builder.blender.org/download/daily/
I'm not able to confirm with normal mouse in 4.0/4.2 builds
Could it be that mouse press for brush execution wasn't released when zooming out? --debug-events command line argument may reveal this.

Yes it persists. See the video recorded with the 4.1 beta from the link you sent.

Thanks for the report, intriguing bug indeed.
Will investigate it soon. I have a regular mouse too, could you try to reproduce it with a normal mouse?
that way we can rule out the spatial mouse interaction and will be easier to reproduce to other devs.

@farsthary hi, I can replicate with regular mouse (video attached in the description might help).
