Plasma tries to load wallpaper in that format, but currently git master of new wallpaper has them in jpg format. Changing the suffix in plasma-framework is not wise, as that will break Plasma 5.1.x Reproducible: Always
Is any VDG effort needed to resolve this or does the dev team already have the wallpaper assets necessary to convert to png? Let us know if there's anything we need to do?
I don't have the original assets. I could convert the JPEGs but that'd be a bit silly. Marco made the commit: "updated version of the default wallpaper from the KDE VDG" I don't know if he did the exporting or someone else did.
Thanks much David. The jpg versions have been repaced with the png version of the wallpapers are now in breeze master. I'll mark it resolved.
