the incorrect scale (left) and expected result (right)

When Plasmashell starts on a Wayland Session with 2x scaling enabled, the wallpaper is over-scaled. This can be temporarily corrected in a session by killing Plasmashell and restarting it (killall plasmashell && plasmashell).

Thanks for reporting. Should be fixed in Qt 5.12

I don't want to do a workaround before then. Sorry.
