Thank you and Paul for pointing me to this patch. I apply it and the strange artefact goes away. Panel isn't 100% yet - sometimes uniform white again after resume from suspend, and I see [ 202.881500] omapdss APPLY error: cannot set timings for lcd: manager needs to be disabled [ 202.881530] omapdss APPLY error: cannot apply lcd config for lcd: manager needs to be disabled which I don't think I saw before, but I'm happy to track that down myself So you can add a Tested-by: NeilBrown <neilb@xxxxxxx> to that patch if you like. Thanks, NeilBrown
