[LibGDX]TiledMap screen tearing

I found a few similar topics on this problem, but I failed to solve it. When rendering a tiled map using API from libgdx or slick2D there are awful white lines across the screen (if camera moves). I tried constraining camera position to integer values, which works but not for scaling. Pre-rendering to FBO gets rid of some artifacts but map still isn’t smooth. Any ideas?
