Created attachment 31296 [details] test case I noticed this while investigating WebKitGTK+'s failure to draw some box outlines. When WebKit tries to draw a 4-points polygon with code similar to the one I'm attaching as test case nothing gets painted. If I comment out the line that sets the antialias type to NONE the outline does get painted. I tried using the image backend to be sure, and it worked when generating a png, which is why I'm filling this under the xlib backend component.
Oh, I just noticed I forgot to explain why I say some paths do not work. If you make the path be a rectangle covering the whole window, for instance, it works.
One more information: it works when running inside Xephyr, but not on my main X server.

I cannot reproduce and based on what you are seeing, it looks like a driver bug. Additional information (like what video card and driver you are using) might be helpful in tracking down the issue, but it probably does not belong to cairo.
