Issue with exporting sprite sheets + transparency

Hello,

I seem to have an odd issue when exporting sprite sheets in v1.2.25-x64. I have used aseprite on/off over the years, so I’m not sure if it is something I only recently noticed or has always been the case.

The image palette is indexed (needs to be) and color 0 is 255,0,255 but set to be the transparent color.

If I export a single frame (file->export) as a .png, the output image background is opaque (255,0,255).

If I export a sprite sheet (file->export sprite sheet) as a .png, the output image background is transparent but when loading into other image editors the background is showing RGB 0,0,0.

Any ideas why?

Thanks,
Mr Biscuit
