This will not show up on a screenshot, so I took a photo. This is an accurate
representation of how unreadable some UI elements get because of this bug
DESCRIPTION
Night Light now turns bright - especially blue - colors to overexposed
yellowish tint. This makes white text on a blue background (e.g. the default
highlight theme) completely unreadable depending on strength.
STEPS TO REPRODUCE
1. Turn on Night Light (Always on night light or Sunrise and sunset).
2. Set the strength to anything from 2,000 K to 1,000 K.
3. Apply.
OBSERVED RESULT
Some colors get strongly overexposed affecting the readability of UI elements,
text, images.
EXPECTED RESULT
Colors' temperature changes to a warmer tone, but they remain readable.
SOFTWARE/OS VERSIONS
Operating System (available in the Info Center app, or by running `kinfo` in a
terminal window):
KDE Plasma Version: 6.8.0
KDE Frameworks Version: 6.31.0
Qt Version: 6.12.0
ADDITIONAL INFORMATION
This problem doesn't happen when HDR is on.
This bug: https://bugs.kde.org/show_bug.cgi?id=515431 - is still relevant when
you set the temperature to 1,000 K without HDR, or when you set it to anywhere
from 2,500 K to 1,000 K on HDR.
