Description Regis 2019-02-11 14:22:51 UTC 
When trying to export a multi layered KRA file to a single layer TIFF file, it fails if the KRA file has layer groups.

In this case it shows an error window with the following message:

"Error: cannot save this image as a image TIFF.Reasons:
-The image contains layers of unsupported type Group Layer. Only the  rendered result will be saved."

At this point, you can just click OK but it won't save anything. You have to manually flatten your image or you cannot export to TIFF.

Yes, I saw that happen recently as well.

> Yes, I saw that happen recently as well.

I think there could be something causing problems with layer groups on a more general scale: I also reported this bug https://bugs.kde.org/show_bug.cgi?id=404200 - could it be technically related?

I've also encountered another bug, just one time (but haven't had the chance to reproduce it yet), where parts of grouped layers had disappeared when I used the transform tool to move groups around... I'll try to find a way to reproduce it.

Fix TIFF export filter to flatten images with group layers

We can still save into TIFF if we flatten the image
