Scanline-like artifacts in 3d scenes #91260

Open aladvs opened 2 months ago

aladvs commented 2 months ago

Tested versions

Reproducible in 4.2 stable & 4.1 stable.

System information

Godot v4.2.stable - Windows 10.0.19045 - Vulkan (Forward+) - dedicated AMD Radeon RX 6800 (Advanced Micro Devices, Inc.; 31.0.24027.1012) - Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz (12 Threads)

Issue description

Strange scan-line like visual artifacts occur randomly depending on visual settings and camera setup.

Steps to reproduce

This occurs in the official godot 3d settings demo (copy attached in MRP)

  1. Open project
  2. Run project in editor or as exported build
  3. Enable 'ultra' settings

The issue can be temporarily remedied by disabling MSAA, but still can occur with it off. Attached is an image with an example of how it looks. image

I've had this too, but only when I exported my project to Windows, it doesn't show in the Editor on Linux. I didn't check it long enough if it still shows after disabling MSAA but it worked for me. Godot v4.2.2.stable - Linux Mint 21.3 (Virginia) - X11 - Vulkan (Forward+) - dedicated AMD Radeon RX 6600 (amdgpu; 6.3.6) - AMD Ryzen 5 3600 6-Core Processor (12 Threads)

Can you both test with 4.3-dev5 (https://godotengine.org/download/archive/4.3-dev5/)? I think this is something that we fixed in 4.3

Yep, also still occurs. For me it's MSAA AND VoxelGI turned on that creates this effect.

aladvs commented 2 months ago

For me, this occurs only due to *2 MSAA. other settings dont seem to affect it
