Created attachment 134685 [details] Screenshot of the bug SUMMARY I just discovered that the Labels column in the Layouts tab of the Keyboard KCM is not empty, but shows layout labels colored in almost white, which makes them barely visible. STEPS TO REPRODUCE 1. Open the Keyboard KCM 2. Go to the Layouts tab 3. Configure layouts to show labels without flags OBSERVED RESULT Label demos are barely visible EXPECTED RESULT Label demos are black SOFTWARE/OS VERSIONS Operating System: openSUSE Leap 15.2 KDE Plasma Version: 5.20.5 KDE Frameworks Version: 5.78.0 Qt Version: 5.15.2
Created attachment 134756 [details] Looks good to me Weird, it looks fine to me (see attached screenshot). Are you using a non-default or customized color scheme?
I use what is now called Breeze Twilight: Breeze for apps, Breeze Dark for Plasma.
Can confirm now. The KCM must be using the text color from the Plasma theme, somehow. Will see if I can fix it.
Found it. The problem is in Flags::drawLabel(), in plasma-desktop/kcms/keyboard/flags.cpp const QColor textColor = flagShown ? Qt::black : Plasma::Theme().color(Plasma::Theme::TextColor); This is appropriate when the label is being drawn on a Plasma widget, but this code is re-used for drawing the flag or text in the KCM too, which is not appropriate.
Will fix.

Git commit e6e11758d255afa78cc0e11ecb1e044d30a25c86 by Nate Graham. Committed on 15/01/2021 at 19:56. Pushed by ngraham into branch 'master'. [kcms/keyboard] Use correct color for layout label in KCM The label was always using the text color from the Plasma theme, which just happened to work fine as long you were using the same colors for both your Plasma and Apps colors (e.g. both dark or both light). But when using one dark and the other light, the text would become invisible. This is resolved by adding a paremeter to the function that allows it to specify whether it should get its text color from the Plasma theme or apps color scheme. Then the function invocation for the tray item asks for the Plasma theme color and the invocation in the KCM asks for the apps color scheme color.
