Rendering issue with integrated GPU but not Nvidia GPU

[TheRektafire]

Description

When loading a default project in the editor I immediately noticed a rendering error where the viewport would be completely white but sometimes gray squares would randomly flicker on the screen in a somewhat diagonal pattern. I figured it might be because Windows is using my laptop's integrated GPU instead of its RTX 4050 so I went into the Windows settings and added a setting for WorldEditor.exe to force it to use the Nvidia GPU, then the problem went away. So the issue is clearly with the integrated GPU.

Prerequisites

Open a project in the editor

Steps to Reproduce

See above

Expected behavior:

Rendering without errors

Actual behavior:

Rendering errors

Reproducibility:

100% reproducibility

Versions

2026.1, though WorldEditor says it's using 2025.3 for some reason....

Additional Information

Laptop: HP Victus fa2082wm
CPU: Intel i5 13420H
Integrated GPU: Intel UHD graphics (GPUZ didn't give me any more information than that, apparently according to techpowerup it;s Iris Xe graphics but not sure....)
Dedicated GPU: Nvidia RTX 4050 6GB

@TheRektafire thanks for the feedback. Could you please check if any shader related errors in Console log?
Screen shot will be appreciated as well.

Oh I forgot to change version of config in build procedure.

So does that mean the world editor is still using 2025.3 or is it just a visual thing? It might just be that the world editor is an older version of the engine and that actually using the newest version would fix it. And here's what the console says currently, it doesn't say anything about shader errors and nothing was output in the terminal I opened the editor in (though maybe it's because I use the msys2 terminal for all my dev stuff and not command prompt

It's a visual. Your commit hash must be 75ba961

On the screenshot I still can see some details it means this it's not completely broken. This issue can be related to one of rendering tasks. I need to isolate it to know the exact place before fix it.

1. Could you please create some 3d objects on the scene for visual check.
2. Open buffer visualization menu (on attached screen) and select a few buffers to visualize and make a screenshot:
   • Normals Map
   • Ao Occlusion
   • Local Reflections
