System information

Godot v4.2.dev3 - Windows 10.0.22621 - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 1650 (NVIDIA; 31.0.15.2824) - Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz (12 Threads)

Issue description

After enabling the HDR 2D setting in Project Settings > Rendering > Viewport and restarting Godot, the colors in the editor change.
I believe this is an alpha compositing issue as described in #80868, since the elements that change are all faded overlay elements (such as the highlight rectangle for the currently selected code editor line).

Aside from making things a bit uglier, this makes grayed-out options even harder to differentiate.

Steps to reproduce

1. Enable the HDR 2D setting in Project Settings > Rendering > Viewport
2. Restart Godot
