Can you show some code?

Tiling such a texture has some problems.

It seems that your texture (for example u-) coordinates are in between 0 and 1/4, then back to 0 (in a small range it results the reversed number on 1 ).

You could write a pixel shader where you use fmod on the texture coordinates like :

uv = fmod(uv,float2(0.25f,0.25f));

This allows you to use a regular texture coordinates and the modulus will keep the texture coordinates in the desired range.

Cheers!

Thank u kauna. As you say, it's a wrong coordinate between 0.25 to 0, Cheers!
