Corruption of fog of war on the map

I'm familiar with the idea that not every bug is traceable and fixable, especially hardware dependent ones. Would be nice tho, to get a confirmation from someone official that the team is aware of this unintended behavior. This has been frustrating me an several other players for a couple years : (

I'm ready to post any game or system file that would be of any help to you

An update

After I explored more of the oceans all the way to the borders of the world the stripe became wider:

When I travel to a different shard and temporary get rid of this map corruption, the fog of war borders acquire angular edges consistent with the map tiles in places where the stripe used to be

 

Also this issue happens in the caves as well if I log out and close the game while being in the caves 

Changed Status to Fixed
