Do all the fltk test programs portray this weird behavior
as well?
Try running 'xrefresh' while your app is running; do the
artifacts change?
Have you tested a lot of other GUI apps with this configuration?
eg. 'old reliable' X apps (like 'xeyes', xclock, xlogo)
Try resizing these real large and real small, looking for
drawing artifacts.
This sure looks like a driver issue of some kind,
the way there appears to be 'echos' of other screen data.
