Actually when I posted I knew it has a small problem, once a day it stops
to work (printing: Hour '24' out of range 0..23). I only wanted to give
you an idea, here is a quick hack if you may tolerate one case:
$t[2]++; $s = $t[2] == 24? 3600000: ((timelocal _at_t) - time) * 1000; \
print "Schedule $s ChangeRootHourly\\n";`

Hmm, I see you use the "desktop" word for 2 different meanings. Which?
I suppose you simply mean it takes some time to see a new image.
Yes, it takes some time to copy a picture to the root window.
I don't think colorsets in FvwmBacker work much slower than xv.
Try also solid colors or simple tiles as your background to speed it.

It is. But I don't know whether there is a good solution in X for this.
