Crash on lower end hardware when resizing window with mouse

[golddotasksquestions]

Godot version

4.1.1 stable

System information

Win 10, latest updates, dedicated Nvidea 765M (2GB VRAM), dedicated Nvidea 1070 (8GB VRAM) both Forward+ renderer

Issue description

On the 765M Laptop Godot 4.1.1 window crashes as soon as I try to resize the Window.
On the 1070 card Godot 4.1.1 drops from ~2100 fps to ~60 fps (vsync disabled) while I try to resize the Window. No crash.

The minimal reproduction scene I tested this has a

Meshinstance3D, (Cube Primitive Mesh)
Camera3D
AnimationPlayer to rotate the cube
WorldEnvironment and DirectionalLight3D to see anything
Label to print the FPS

I have tested this with just the MeshInstance3D and Camera3D with the same result.
Except for disabling vsync, everything else is default. I have also tested this without disabling vsync and the crash on lower spec hardware is the same.

Possibly related: #79446

Steps to reproduce

1. Run the MRP,
2. resize window with mouse

Can you please test on Dev 2 as well? https://github.com/godotengine/godot-builds/releases/tag/4.2-dev2

We just merged #79884 which appears related to this bug

It seems like Godot 4.2 dev2 improved things noticeable, the window does not seem to crash anymore on the lower end hardware, but performance still tanks on both GPUs.

On the 1070 the performance drops from ~ 1850 to ~ 60 fps while resizing
One the 765M it's a slideshow while resizing and the Editor in the background gets this weird theme sickness (colors and UI textures changes are different each time):

This may have been partially fixed by #80571

We should have a new dev builds for testing available soon
