Hi,
i was under the impression that mergedimage.png saved inside kra file was the final image.but it seems to be missing filter layers.
the preview.png file looks as expected but 'mergedimage.png' is missing some filter layers.

is this by design?,a bug?,is there some setting i can change so that the final image is saved.

thank you.

That should not hapen. Please report a bug and make the actual .kra file available. Make sure to mention the exact version of Krita you are using and the operating system.

Ok thanks,i submitted bug report : https://bugs.kde.org/show_bug.cgi?id=400427
