[0.13.3][posila] Map-Pollution Bug

[BestMan]

Having a different view of the map messes with the pollution shown

[gir]

Same problem here on a map created with version 0.13.1 and played with 0.13.1-0.13.3.
The pollution shown on the map is in my case clearly inaccurate and periodically (~0.5s) flickering on the outskirts but not like it normally (reffering to 0.12.x) did. The "bugged" pollution also triggers biter attacks.
There are vertical stripes with no pollution at all going straight through my factory. When changing the view (zoom-in/out and moving) the pollution sometimes is consitent (aka not bugged) and sometimes inconsistent (aka bugged).

Screenshots

Unedited screenshot of the map:

Edited to show the "bugged" pollution:
The filled turquise areas are where it is periodically flickering. The striped area is "steady" pollution.
Noticable here, there are vertical stripes with no pollution at all going straight through my factory.
