Thunderbolt dock disconnects when opening bevy engine. (help?) (piefed.social)

Hi, I'm relaying a problem my gf is having. She has an acer laptop with Intel + nvidia hardware and a ThinkPad Thunderbolt dock. Running arch with kde. Whenever she starts bevy engine, including its demos, the dock disconnects and reconnects, causing everything connected to it to also do the same.

The journal has some GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT errors but I also have some in my journal so I think they aren't specific to bevy.

I don't understand how a user program can cause such an issue. Even if bevy has a bug I don't think it should affect peripherals? Has anyone seen something like this?

Now solved: this was a power delivery issue where if the power draw for the machine got too high and the laptops dedicated power brick wasn't connected, the dock would try and fail to deliver the amount of power needed, trip over itself, and end up shutting down entirely instead of just not delivering as much power.
