[4.3 Beta 3] Strange editor brightness and colors caused by RTX Dynamic Vibrance affecting the editor

[Xephyrose]

Tested versions

Tested with v4.3.beta3.official [82cedc8], seems to happen as far back as v4.3.beta1.official [a4f2ea9]. If I use v4.3.dev6.official [89850d5] or older, the issue is no longer present.

System information

Godot v4.3.beta3 - Windows 10.0.19045 - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 3060 (NVIDIA; 32.0.15.5612) - 11th Gen Intel(R) Core(TM) i5-11600K @ 3.90GHz (12 Threads)

Issue description

In Godot 4.3 Beta 3, the editor is quite a bit brighter (4.2.2 Stable on the left, 4.3 Beta 3 on the right)

It seems sometimes clicking some things will change the brightness or color of the editor very subtly as well, as shown here:

Godot.Engine.2024.07.11.-.15.28.05.05.DVR.mp4

Steps to reproduce

• Open Godot 4.3 beta (1-3)
• Open a project (can be a new / empty one)
• The editor will be bright as shown in the picture

Do you have HDR enabled on the desktop? Do you have RTX HDR enabled?

Also, do you have G-Sync/VRR enabled? Try disabling it.

RTX HDR affects the Godot editor, but once it becomes idle for a few seconds, it will no longer affect Godot unless Update Continuously is enabled in the Editor Settings.

If there's a way to disable RTX HDR (and RTX Dynamic Vibrance) on a specific using an application profile, it might be worth making a PR similar to #93737 so that it's never active on the Godot editor. It should remain usable on exported projects though (and perhaps projects being run from the editor too).

It seems that it was caused by RTX Dynamic Vibrance.
