I was playing with mod Ultracube, which provides a camera view around where a cube is located. When player is near the cube, the player's normal game view will have some area overlapped with cube's camera view, and belts inside this overlapped area will flicker.

I've attached a video showing this issue. It happens on both my 1080p and 4k monitor.

I can confirm the issue, although it happens a lot rarer for me.

It's most noticeable when the camera view is zoomed in and gameplay view is zoomed out, and when there are items on belt. The belt seems being switching between empty and loaded.

Thanks for the report however there is no known solution for this that won't have a large performance overhead.

Can you tell what causes this?

The two game views (normal, and camera) render the world in parallel and the belt rendering logic has some internal values that get used to avoid over-drawing belt items. Which ever game view gets to the belt first that frame gets to draw the items.
