Color distortion in drawing with plot

In a Linux system, the version of MATLAB I use is 2015b. The pictures drawn with plot seem to have some wrong colors. I don't know why.

For simplicity, I used the pot function to compare with the MATLAB of the window system. As shown in the figure below, I used the plot (1:100, 'R') function to display a red straight line. After the image displayed in the Linux environment is enlarged, it is obvious that the color is distorted, the image seems to be rendered, and there are some stains around the line。

Thank you very much for reading my questions and looking forward to your suggestions

Looks like a renderer problem. I suggest you try different renderers. But a better suggestion would be to make that 7 year old dinosaur go extinct and upgrade to the latest version.

What does this say?

plot(1:10, 'r-');
ax = gca;
info = rendererinfo(ax)
opengl info

Thank you very much for your reply. The display is as follows:

Can you see any problems from this information?

I have Windows and it doesn't have the Mesa X11 renderer. Try to find out what other renders are avialable to use. Call tech support if you need help with that.

Thank you very much for your patience. I'll try the relevant settings.

BTW, I found that computers that display no problems also use the same renderer

I checked, "mesa X11" is an OpenGL software renderer, which is mentioned in the help document of MATLAB

Are there other renderers you can use? Maybe it's a problem with your specific graphics card.

How do I switch the renderer?

[Image Analyst]

If you're using GUIDE, it's one of the properties of the main figure (the background space on your GUI). I'm not sure about app designer. Otherwise, call tech support or dive into the documentation.

I can also choose painter as the renderer, but there is no change.：

Well I can't see it but maybe if you zoom way in you can. It could come down to your graphics card adapters. Try updating your drivers.
