Description Alvin Wong 2021-09-07 10:05:33 UTC

In "Split alpha" -> "Save merged", the file type "all supported formats" is selected by default, and ".exr" is the first extension in the list. This means if the user doesn't enter a file extension, exr is used by default.

Due to EXR's use of premultiplied alpha, it may mangle the colour data of transparent pixels. It seems to me if the image is 8-bit per channel then having PNG as default would be the better choice...

I've removed the all suported format entry now. See https://invent.kde.org/graphics/krita/commit/362feb5d0cc25a7d16e5723a0081da85125b0514
