various programs when paint a circle show some horizontal lines Reproducible: Always Steps to Reproduce: 1.Open a program than use the x11 library for draw a circle (eg.: kicad: eeschema, qucs) 2.Make the program draw a circle (eeschema: some connector, qucs: a power source) Actual Results: the program show a circle with glitches Expected Results: a clean circle I see this behavior in eeschema

Does downgrading to x11-libs/libX11-1.4.0 fix the problem? In other words, does libX11 or one of its versions cause this specifically? Also, could you attach those screenshots to this bug report?

I attached the screen shots. About the version of libX11, this already happened since 1.3.6 according to the first post in the forum. (http://forums.gentoo.org/viewtopic-t-852991.html) Also, I'm making a emerge -1e with gcc-4.4.5 but with no luck
the rebuild of the system with gcc 4.4.5 had no effect. This bug can be caused by -O3? as a side note, I have 2 PCs with almost the same configuration and both have this bug so most likely it isn't a damaged hardware problem.
after emerging with -O2 this problem is gone
