Uh.. It's (among others) testgtk that's flashing.. 8/
I've tested showing onto an AIX-display as well, so it's not Xsun's
fault..

Seems like it tries to change to the correct colormap, then reverts to
the default.. just enough to flash annoyingly... This happens when the
color-sel is about to recieve/lose focus..
