Hi. I get an error sometimes when attempting a screen capture:

xwd: Warning. Error in XWD-color-structure (flag)
xwd: EOF encountered on reading
xwd: load_image (xwd): XWD-file /root/.gimp/tmp/gimp_temp.277523.xwd has
format 2, depth 24
and bits per pixel 24.
Currently this is not supported.

What's this trying to tell me?

Strangely, sometimes screen capture has a problem and sometimes it doesn't.
If Netscape is up on the screen then screen caps tend to work better. Why
would this be? I'm trying to capture screens containing video players so I
can show what the players look like. I can capture (with difficulty)
everything but Xtheater. The players are paused when I do the capture.

In a perhaps related issue, I can't get xvidtune to bring the screen down to
the bottom edge of my monitor. With the DefaultColorDepth set to 24 my
screen rate was 115 hz, but at 32 it is just 85 (max available is 86). What
does choosing 32 or 24 signify? Isn't 24 bits per pixel as much as there
actually is?

At 85 hz I can almost (but not quite) get the screen to fit to the edges of
my monitor. Using 85 hz in Win2k/NT/98 booting on the same machine works
fine. In XFree86 3.3.x Potato there is a half inch of black left at the
bottom edge I can't get rid of. Why not?

Thanks! Relevant sections of XFree86Config below.
