This bug may be fixed like bug #47858 (wrong line joins)

Yes, looks like it. That would be bug #32980. Ok to close as a duplicate unless there is some interest in keeping this open.

Example workaround, decimating the series by a factor of 10:

Isn't this the notorious single-precision "bug" in OpenGL? several bug reports and duplicates have been entered for this one.

Dear developers

When the figure below is shown on screen it is correct, when printing to .pdf, .eps or *.ps the noise level is to high.

Problem only shows when using a large data set.

If there is no initial noise, there is no problem.

Problem does show with graphics_toolkit qt and fltk,
it does not show with gnuplot.

The problems shows on two different Linux hosts, with versions 4.0.0 and the developer version of Octave.
