System Information
Operating system: macOS-12.3.1-x86_64-i386-64bit 64 Bits
Graphics card: Metal API AMD Radeon Pro 5500M 1.2

Blender Version
Broken: version: 3.5.0, branch: blender-v3.5-release, commit date: 2023-03-29 02:56, hash: 1be25cfff18b
Worked: (newest version of Blender that worked as expected)

Short description of error
When working in the 3D viewport, when in Wireframe mode and Xray mode is OFF, clicks to select an object are passed through and select objects behind the object. It's very difficult to select the object whose intention it is to select.

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]

Hello Christopher!

I know its not much help, m trying to reproduce this, but im on windows, here its work that im click the first in a row object its select normally, and if click again its jump the next behind. It worked with and without gpu depth and without selection in settings.

Hi, thanks for the report. Can you check whether GPU Depth Picking is enabled in preferences?
Does this issue happen with both Metal and OpenGL viewport backend?
Can you share .blend file?

AH! That did it. GPU Depth Picking was enabled, I'm guessing by default(?). When I disable it while using the Metal backend, selection now works predictably in Wireframe view without Xray on.

My workaround was to switch over to Shaded view as selection seemed to work correctly there.

I can share the project if you need it.

I just did a test where I switched over to OpenGL for the backend, and enabled GPU Depth Picking. With these conditions, selection is correct in Wireframe (non-Xray).

However, if I turn off GPU-Depth Picking in OpenGL, then it has the same selection problem (picking items behind what you are trying to select).

ok, thanks for the update. With GPU depth picking, visible object is expected to be selected first.
So If I understand correctly, problem is with Metal backend.

Yes, please share a simplified version of it.
