Hi.

When I applied it and want to finish my work i merge visible it goes back as i didn't do anything,is that correct,I think it"s not.

If you're using a Live Unsharp Mask can you just try unlinking it from the layer it's applied to, then trying Merge Visible again to see if the result is different.

Hi Lee.

Thanks for your reaction.

But it does not help,i put live filter above the layer and merge visible  no succes

thanks in advance

You do need to view the image at 100% to see the effect correctly.

At the first plac,thanks,it is indeed better,but why it must be at 100 %?

It is hard to explain without going into a lot of technical details but basically it is because to display any 'live' effect (adjustment, filter, whatever) at 100% accurately at any zoom level, everything that affects must be re-rendered at that zoom level. That would take a ton of CPU/GPU resources during 'on-the-fly' zooming, which would mean smoothly zooming the display would tax all but the most powerful systems, which in turn would result in long delays on most systems before the display could be updated to show the document accurately & anything else could be done after zooming.

The Affinity apps use some novel "under the hood" techniques to avoid this delay & provide very high speed & very smooth zooming , but the tradeoff is not everything will be rendered on the display accurately at every zoom level.

Thank you very much for effort to help and explaining.
