Comment (by tkeitt):

 I have not tested this lately. It is _not_ a QGIS bug. It is a bug in the
 Xserver. I have generated a backtrace and filed a bug with xorg. This
 (QGIS) bug can be closed because it does not occur in the QGIS code. The
 backtrace indicates that the bug is in the polygon filling algorithm used
 in X. As best I can tell that code was written at MIT in 1982!
