I meant to suggest patching Xorg, but this zorks just as well.

I don't know what fceux is, nor do I know how SDL works. I do have a
hunch that the black rectangle is a hack fceux' SDL uses to obscure
other windows (so they won't repaint themselfes), or some
pseudo-input-only (with output) to get around some limitation in X11
instead of using proper input-onl windows.

This got me the information I wanted, even if by slightly differently
from what I had in mind.

I don't understand why exactly fceux creates this window, though.
