Curvetexture behaves differently after release of mouse button
Godot version
4.3 rc1
System information
Godot v4.3.rc1 - Nobara Linux 40 (GNOME Edition) - Wayland - Vulkan (Mobile) - dedicated NVIDIA GeForce RTX 3050 Ti Laptop GPU - 11th Gen Intel(R) Core(TM) i7-11370H @ 3.30GHz (8 Threads)
Issue description
I'm sorry, but Gnome currently doesn't record the mouse cursor, but even if it did it wouldn't show when I'm holding the mouse button down, so you'll have to pay attention to the curve point and its highlights instead:

I hope it's obvious that the 3D viewport looks quite different depending on when I'm moving the mouse, vs when I'm releasing the mouse.
Also, the first time I drag the mouse button in the corner I get the weird light colors, but the second time I drag it into the corner I get the "good" colors.
Steps to reproduce
Here's where things get tricky... when I tried to create a minimal project, I wasn't able to replicate this:

However, when I launched my main Godot project again, I got a slightly different behavior:

Minimal reproduction project
Ok, sorry I'm writing this in realtime now... the second time I launched the minimal project I did see the behavior, so here it is:
