    Well I could be wrong, but this seems the most likely explanation, since there is no flicker when running on Emuzwin, Realspec, Specemu, or Klive. Also it runs fine on a real 48K spectrum.

    I just checked which version of SPIN I am using and it is 0.504. Tried it with different combinations of video settings but can't get rid of the flicker. Is there something else I'm missing perhaps?
