Thanks, it makes sense. I understand how combinator works, didn't realized that input/output signals in GUI reflect current tick state.

When input signals are changing fastly, output from decider combinator GUI can mismatch its input.

How to reproduce: In attached picture, two selector combinators select one random signal from one constant combinator with A=1 B=-1, their ouputs are wired into a decider combinator that only ouputs ...

In the middle pictrue (middle zoom level), the width of vertical red wire becomes 3 pixels thick, zoomed out (picture 3) it becomes 2 pixels thick, but zoomed in it becomes thinner as 1 pixel, while in almost any other zoom level and other orientation, the wire is 1 pixel thick. I understand it's ...

When wires are exactly vertical, they become thicker even when zoomed out. It becomes very noticeable in modded games where tiles can be bright and less noisy.

ok, it's a reasonable decision.

I dragged production screen to one half side of game window in remote view while watching my space platform moving to shattered planet, but after switching focus out of the game window and open it back, the production screen came to center.

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.

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 ...
