Thats because it's sitll rendering at various zoom levels, i made border 
from wikimedia, shorty (2 days) after that slovenian friend uploaded GURS 
border, much precise from mine. Than I've deleted my rough border but i 
left disputed part on sea (Bay of Piran).

Because some parts of the border (notably maritime and along shifting
rivers) are disputed and we try to represent this fact in OSM instead
of using OSM as a battlegrund to find or define the one and only
truth. Disputed parts are tagged
disputed=yes
and it is also mentioned in the name (eg Border SI-HR (Disputed)) to
make it clearer.

Of course most parts aren't disputed and in such cases the better
source could probably be used. One is an import from wikimedia (with a

 Hi, I'm from Croatia and I have seen something strange when looking at
 borders. If you look at this map you will clearly see borders:
 http://www.openstreetmap.org/?lat=45.2lon=16.51zoom=7layers=B000FTF

 But if you zoom in or out the borders start to dissapear, especially
 between Slovenia and Croatia. Any ideas why is that happening?


It's in most cases always the same reason why you get an object only in 
some zoom levels, the object got changed and the the object will 
disappear/appear on new rendered tiles.

This is for example new
