Saving files in WebP format doesn't mixdown layers
GIMP version: 2.10.12
Operating System: Windows 8.1 (amd64)
Package: Installer from gimp.org
Description of the bug
I created an project with couple of layers in it. And, I exported the image into a file with WebP format and the exporter seems to pick the most lowest layer (doesn't compose all the layers beforehand) and export it.
For workaround of this issue I flattened all the layers beforehand exporting to a WebP file.
Reproduction
Is the bug reproducible? Always!
Reproduction steps:
- Create a Project with multiple layers in it.
- Export the image into the WebP format.
Expected result: Exports the most lowest layer in the Project without mixing down all the layers.
Actual result: The actual result is the same as the expected one.
