    Hi @marqs, that’s right I have applied the GPIO tiedown mod, which resolved instability with the scaler on 0.60.

    The instability in 0.61 is very different, the image drifts right horizontally from the bottom of the frame without losing sync and without the same kind of jitter, when first powered up, until after a few seconds when the sync is lost.

    This is what made me think it might be performance related, it’s as if each line isn’t being rendered in time, and performance is being throttled more as the FPGA heats up – this is obviously just a guess on my part though. Power cycling doesn’t help much, sync is then lost almost immediately.
