Well, it may be regarded as a low priority visual bug. I only reported it because it is rather jarring.
The fonts are "correct" but because the hinting interacts with the darker background it essentially looks like a monochrome (black and background) font instead of having the gradations of grey that fool the eye into registering smoothness. -- Font rendering bug in Gnome Control Centre sidebar https://launchpad.net/bugs/84346 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
