i've attached the image of a meshplot and some line diagrams as they
appear on my laptop (intel graphics). If the line width is set to 2 or
greater, everything is fine. For the standard line width and line width
1, the colors are somehow twisted.
It happens with 4.2.2 (comes pre-installed with Fedora Core 27) and the
behavior is the same with a build made from the last mercurial
I really do not know what else I could do. If anyone has an idea, please let me know.
