Textures problem, bad texture files

I try to get a nicely distributed texture on a curved surface.
The results are not clean, so I tried with a planar surface.

But even on a planar surface my results are not ok:

Of course round dots are expected.

C:\Users\Charles\AppData\Roaming\McNeel\Rhinoceros\8.0\Localization\de-DE\Render Content\Texturen\Diagonaler Punkt.png
