Surface aliasing (W/ and w/o filter FXAA on)

Dear paraview user,

I have a problem when rendering my file as a surface. It seems that I have an aliasing problem even if the filter FXAA is on in the rendering option.
I can’t give the full file here but here an example of my problem it seems to happen on all faces except one. I am sorry if it isn’t detailed enough. I’ll try to add a dummy example later if the problem is not an obvious thing.


Any idea what could be the problem ?
could it be A graphic card problem ?


My data were badly sorted in my vtk file.
The increasing coordinates order of column 1 (x), then 2 (y), then 3 (z), was not respected causing trouble for reading to paraview.
