[0.16.51] Faint lines on flooring blueprint

-Minor Bug-

I was expanding the area of my base both covered by roboports and reinforced concrete and noticed feint white vertical and horizontal lines in the blueprints which change position depending on what zoom level I am on.

I initially thought that it was outlining the chunks however they can also change spacing depending on the zoom level as well (as shown in screenshots).
This is the first time that I noticed the lines.
While I am wearing night vision, taking it off doesn't change it.
I reloaded the game and they still appeared the second time.
I have tried it with stone and normal concrete blueprints, same lines in same places as reinforced concrete, does not appear to occur on regular blueprints.
I placed all the blueprints from the map view using a single large blueprint of reinforced concrete, clicking and dragging while pressing the movement keys.
The only debugging thing I have activated constantly is the fps/ups counter.
On approx. the 8th lowest zoom level (8th most zoomed in) (using the scroll wheel) I was getting horizontal lines evenly spaced 2 tiles apart in some places (mostly near the bottom right of the area). When zoomed out more I was getting them 4 tiles apart.
I have verified the integrity of the game on steam and got the same results.
I have completely shut down steam and restarted it (closed everything steam related in task manager), still occurs.
Lines only occur on placed blueprints, the green overlay of a blueprint does not produce the lines (they can be seen through it when hovered over the lines)
Lines also appear when viewed from the map screen.

Looks like a rounding error. Trying to perfectly align two partially-transparent objects (e.g., tile ghosts) sometimes creates a one-pixel 'seam' in the texture. I'm betting on it already being fixed for 0.17 as part of the graphics overhaul.
