I was placing a roboport grid, and noticed that the preview of the roboports does not perfectly line up with the pixels of the existing roboports.

Here's an image to show what I mean:

I expected that when I hover the existing roboport grid with my blueprint, there will be no pixels "peeking out" from random spots behind the overlapping area.

Here's the blueprint string I was using:

Minor visual bug. I think it may have been like this for a while as I recall seeing it before, but today I realized it's probably not intended.

Actually I think it may affect all things? The pixels on poles and lamps look misaligned and inconsistent too, although its harder to see those.

I don't think this is a bug, as when you zoom in to normal view, you can usually see the ghost as well as the real entity underneath it. I suspect this is done by offsetting the position of the ghost slightly, which is what you see on the map.

It seems to depend on zoom scale; position of the blueprint (not the entity); whether the entity is in radar coverage; and when it does happen, it affects the whole horizontal/vertical line, not just one entity, regardless of BP's h/v position.

Offsetting the position slightly so the entities beneath are visible would make sense. However, the thing that makes me think "this must be a bug" is that the offset of the pixels is inconsistent between different roboports.
Some roboports are peeking out from the left top. Others, only the top. Others, not at all, etc. That doesn't seem like it's intended behaviour.

Your screenshot illustrates this well. :>

Thanks for the report. Unfortunately this is going into minor issues since there is no clear solution for it. The way the map is rendered is slightly different than the way the blueprint preview in the chart is rendered and they don't always pixel-perfect align at different zoom levels.

No problem, fully agree it's minor issue. Thanks for the reply :>
