Texture tiling problem

[35290-näyttökuva+2014-11-15+kello+15.21.11.png|35290]

I have a plane in 100000 * 100000 scale with tiled texture but something is wrong. What is this?

Probably the scale is way too big so the UV precision is lost. Use a much smaller plane; you can use multiple planes if you need a bigger area.
