dark font color and dark background

Hello,

I use archlinux 64 bits, Plasma 5.10.1, with oxygen theme,

since plasma 5.10.0 I notice that the logout screen is badly rendered when the oxygen theme is used,

the background color is too dark ( dark blue ), as the font color is also dark ( dark grey ) then the readability of the text ( reboot, shutdown, halt ) is very difficult ( see my screenshot ),

it seems that the oxygen package doesn't have a "Logout.qml" file, it uses the breeze version ( usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/logout/Logout.qml ), which can explain the bug,

in usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/logout/Logout.qml file this line 120 triggers the bug :

        //use "black" because this is intended to look like a general darkening of the scene. a dark gray as normal background would just look too "washed out"
        color: root.rgbToHsv(PlasmaCore.ColorScope.backgroundColor).v > 128 ? PlasmaCore.ColorScope.backgroundColor : "black"

if I delete this line and replace it by this then all is ok :

color: PlasmaCore.ColorScope.backgroundColor
