Godot crashes along with Nvidia driver making system unstable on Nivdia Optimus Linux system

[MateusRodCosta]

Godot version

v4.1.1.stable.flathub [bd6af8e0e]

System information

Godot v4.1.1.stable (bd6af8e0e) - Freedesktop SDK 23.08 (Flatpak runtime) - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 1660 Ti (nvidia) - Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz (12 Threads)

Issue description

Apparently currently running Godot 4.1.1 (Flatpak, host is Fedora Silverblue 39 Beta) on my system always ends up with eventually Godot stopping responding and the Nvidia card (driver is 535.104.05) crashing until I reboot.

I do not know if it's a bug in the Nvidia driver or in Godot, so I'm filling an issue here.

This Godot crash apparently can bork both the iGPU and the dGPU:

Steps to reproduce

Basically, opening my current project (It's a Godot 3.5 project I converted to Godot 4.x) and trying to do stuff for a while (for example, I have been working on improving the graphics on that project).

After a while Godot freezes and, when it is killed, the Nvidia card is borked.

Minimal reproduction project

N/A

[s0ra]

I'm using Godot 4.1.1 and NVIDIA GeForce GTX 1660 on Ubuntu 22.04.3 LTS with the proprietary driver. Also I'm using dual screen and x.org desktop. Occasionally the editor will freeze mostly during debugging and the screen will appear glitched from top left to bottom right. I had to logout and login back to recover the computer. This issue never happened to other applications.

Can you test https://github.com/godotengine/godot/pull/80566 locally to see if it resolves the issue?

Also, can you reproduce this using all rendering methods, or only Forward+/Mobile?

[MateusRodCosta]

I actually have been using v4.1.3.stable.flathub [f06b6836a] for a tutorial recently and I had no issue with crashes.

One thing to note was that the project was set to Compatibility renderer, so I have yet to test if the issue is specific to the Forward+ renderer.
