Sadly, the current design doesn't really allow for arbitrary wallpapers (and since is possible already to put any image, that's quite a problem) if a wallpaper should become the default again, the text elements should either have a visible background for contrast (so would mean a pretty heavy redesign) or, showing only the wallpaper by default and only after mouse move/any interaction the actual controls appear and the wallpaper gets either completely covered or with an heavy blur+contrast (blur alone isn't enough to ensure readability of text, the shader should modify the colors as well, like the plasma panel does) there are several options for that, but all will mean some rewrite, in order for it to look like a godd quality product. So now the challenge is i guess arriving firt with a good design which is not too big of a departure, doesn't look too busy, and works well with any wallpaper.. sounds like a fun challenge :) btw, for reference, the current is https://phabricator.kde.org/T2062 REPOSITORY R133 KScreenLocker REVISION DETAIL https://phabricator.kde.org/D11308 To: ngraham, #plasma, #vdg, graesslin Cc: mart, graesslin, plasma-devel, ZrenBot, lesliezhai, ali-mohamed, jensreuterberg, abetts, sebas, apol
