Obsidian flickering on 4K external screen with more than a couple notes open

Hi there. This is more of a request for suggestions from the community.

What’s happening

I have a MacBook Pro that is connected to a LG 4K screen using a Display Port cable. I noticed that when I move Obsidian over to the larger screen, and have more than 3 or 4 notes open, Obsidian flickers for me with each movement, switching between notes, and typing.

If I move Obsidian back to my MacBook Pro’s main screen, I don’t experience this issue at all.

I feel like this is an issue between my laptop and the screen, and I’m curious whether anyone has any suggestions for address this? Is this an issue caused by my external screen’s resolution, my MBP’s capabilities, or both (perhaps)?
