Summary [CAIRO] Fails to paint solid outlines

Summary says it all. I was able to track this down to a Cairo xlib backend bug, in fact, but we may want to work this around somehow. See: https://bugs.freedesktop.org/show_bug.cgi?id=25167 Commenting this line in GraphicsContextCairo.cpp::drawConvexPolygon makes it work: cairo_set_antialias(cr, shouldAntialias ? CAIRO_ANTIALIAS_DEFAULT : CAIRO_ANTIALIAS_NONE); I am not sure win32 cairo suffers from this. I would bet not.

It works here, but I'm not exactly on master here. What cairo version is that? And your rendering is just the same only without the big black box?

Also works for me. Cairo 1.8.8 here.

(In reply to comment #3) > It works here, but I'm not exactly on master here. > What cairo version is that? 1.9.2. I have now tried with 1.9.4, and 1.8.8 with the same problem. May be related to my version of X, perhaps, or of pixman? > And your rendering is just the same only without the big black box? Exactly.

Interestingly, the problem does not happen when I run GtkLauncher inside Xephyr, so hrm.

(In reply to comment #7) > Are you still seeing this issue? No, might have been fixed by an X/cairo upgrade, so I'll close it =)
