Hi Eckhard! >As it seems the timer loop always expires >after cycle 70 or so. One timer step is only >64 cycles, so if you reduce the timer value >by 1, you should always get a stable picture. The thing I realised in the meantime is, that the end cycle where the timer expires can only shift between 5 cycles, right? So I shifted the point where the timer is loaded some cyles (> 5) later, which should have the same effect as reducing the counter, right? >> And why is Z26 not jerking? >Because we are not really sure when the jittering >is supposed to happen and when not.

I think this'd be a cool & necessary feature, at least for us developers.
