Graphical problem with Spacebuild map New_Worlds2

Now before I start let me just say, sorry if there is a topic regarding this, but I couldn’t find it and the search feature isn’t working at the moment…

Anyways, My problem is, is that when im playing New Worlds2 (heck I had the same problem with New_Worlds) Its kinda hard to explain the problem, so lets look at some pictures…

That picture is what I believe it should look like

And those are what it looks like when I move, as you can see this would be really annoying and cause most to rage quit and throw things…
The first picture is just me moving slightly, and the second one is what it would look like after moving for several seconds.

Anyone have any ideas as to what’s wrong and what I can do?
I’d really like to not have to avoid the map, it actually seems pretty cool…

Oh and so I don’t get banned (since i read the rules)
