Problem with Tilemap Texture Loading (solved)

(Please apologize my english if its bad)
I have a really anoing problem with the 2d tilemaps. Im using levelstreaming to load between different levels. When i load for example level 1, everything is loading correctly except the tilemap. The tilemap needs approximately 4 more seconds to load and that looks really ugly (as you can see in the screenshot). Does someone have a solution for this Problem? I couldnt find anything about that.
(If you need more information about my project, just wirite it).

Never mind i sloved the problem. I just had to turn off texturestreaming. No joke, it took 6 hours or more to find it out, because i couldnt find anything about that issue with the tilemap.
