System Information
Operating system: Windows-10-10.0.22621-SP0 64 Bits (Windows 11 Pro 22H2)
Graphics card: Radeon RX 580 Series ATI Technologies Inc. 4.5.0 Core Profile Context 22.10.3.221025 (Sapphire Nitro+ 4 Gb VRAM)

Blender Version
Broken: version: 3.4.0, branch: blender-v3.4-release, commit date: 2022-12-06 18:46, hash: a95bf1ac01
Worked: 3.1.0

Short description of error
Every time I use clipping regions (the Alt+B tool), everything outside region is full of artifacts and some areas inside too. This error only occurs when overlays are displayed, if you hide overlays it's gone (see below). This tool worked perfectly on Blender 3.1 and started working like this on newer versions, I think it started on 3.2 or 3.3 im not sure. My graphics drivers are up to date, this error occurs with any file with default settings and as I said, this worked as intended on 3.0 and 3.1 version.

Overlays on:

Overlays on except floor:

Overlays off:

Exact steps for others to reproduce the error
Open Blender with default settings and scene.
Make sure Show Overlays (Shift+Alt+Z) is on.
Use Clipping Regions (Alt+B) anywhere.
If you're using a Radeon Rx580 or maybe any Ellesmere based GPU you should be seeing artifacts everywhere in the viewport.
