I use the X server's screen saver with blanking disabled, the one that draws 
the big X logo on the screen.

Once the saver starts, the logo (solid white on a black background) appears in 
some cycles, and is gone in others (leaving a completely black screen).

Having the logo intermittently disappear somewhat defeats the purpose of the 
saver's blank/noblank option. I prefer to have the logo appear, as visual 
confirmation that the monitor is on.

Looking at dix/window.c, I notice that the logo's color is randomly chosen to 
be either black or white, with black heavily favored. Is it possible that this 
code has remained unchanged from the days when the screen saver drew a stippled 
background? A black or white logo would be visible in that case, but now that a 
plain black background is used, only white would show. Perhaps the logo should 
be drawn unconditionally in white?
