testcase
PDF generated from the document showing the bad rendering.
I thought I uploaded the PDF. Sorry about that.
This is a bug in poppler the library we use to render pdf files. Please report a bug at https://bugs.freedesktop.org/ |
PDF gradients are incorrectly rendered in Okular. Reproducible: Always Steps to Reproduce: When rendering the PDF file generated by pdflatex from this source: \documentclass{standalone} \usepackage{tikz} \usetikzlibrary{shadings} \begin{document} \begin{tikzpicture} \shade[shading=color wheel, opacity=.6, shading angle=220] (0,0) circle (1); \end{tikzpicture} \end{document} Actual Results: Okular renders this incorrectly: grid lines and very bad gradient resolution (see screenshots). The grid lines disappear when "shading angle=220" is removed from the source. Expected Results: The gradient should render smoothly (see screenshots) IIRC, I reported a bug about this to qpdfview, which didn't show the grid lines as okular does, but did show a squar texture pattern, albeit interpolated.
