Terrain3D flickering when using motion blur

Godot Version

Godot 4.3

Question

I am currently making a game that uses Terrain3D and SphynxMotionBlurToolkit. Without motion blur enabled the terrain is fine but when enabled it will flicker. I saw another post on the Godot Forum about flickering and it looked exactly like my issue except they were experiencing the issue because physics interpolation was on in Godot 4.4 dev 7.

The issue seems to get fixed when I use the Heightmap Terrain plugin rather then Terrain3D.
