Hello Joachim, hello Brian,
I noticed the same behaviour of unicode-screensaver and tried to fix it -- I
think what might have been missing was the initializiation of the PRNG with
some seed. The following patch works around this issue by using
arc4random_uniform() instead of random() (according to arc4random(3) this
avoids "modulo bias") from libbsd-dev (what would be another dependency, tho).
HTH and greetings,
Stephan
