STEPS TO REPRODUCE
1. Set global theme to breeze dark
2. Go to login screen (sddm) configuration in system settings
3. Click apply plasma settings (not the normal apply button)
4. Log out (not lock, lock works properly)
The login and password input fields are white which makes the typed in text invisible (but it is typed in, you can mark it).
The input fields should be dark and the text should be light.
Linux/KDE Plasma: KDE neon 5.24
(available in About System)
KDE Plasma Version: 5.24.5
KDE Frameworks Version: 5.94.0
Qt Version: 5.15.4
The described behavior happens only when the apply plasma settings button is clicked in sddm settings. When doing the same thing in the settings when breeze light or breeze twilight is used, the input fields are light and the text is black (as expected). The problem is only with the dark theme. It looks like the text color is changed to white, but the input field color isn't changed to dark.
