Extreme CPU usage when no dedicated GPU connected

[OneBiteAidan]

2020 Dell XPS 9500
Core i7-10750H @ 2.60GHZ
16GB 2933 DDR4 Memory
(No dGPU enabled by default)

I have an external GPU that I use for gaming at home (ASUS TUF GAMING RTX3070 in a Razer Core X thunderbolt enclosure). When I disconnect my laptop to take it to school (leaving the laptop w/ just integrated intel graphics) I notice my mouse skipping around the screen. VibranceGUI also uses between 10-25% of my CPU depending on how early I notice the mouse skipping.

Hi, can you make a screenshot of what it looks like when vibranceGUI is trying to initialize but your GPU is not connected to the laptop?
