Description svc.kde 2020-05-21 00:33:45 UTC 
SUMMARY
The lock screen clock fails to respect the system's font antialiasing settings and always uses RGB subpixel antialiasing, even when everything is configured to use grayscale antialiasing.

STEPS TO REPRODUCE
1. Switch to grayscale font antialiasing in System Settings -> Fonts
2. Re-login to make sure the font rendering change takes effect
3. Lock the screen
4. Look closely at the clock or date

OBSERVED RESULT
The clock and date at the top of the lock screen are rendered using RGB subpixel antialiasing. This can be verified by carefully looking at the edges of the text in a screenshot if the difference is not clear.

EXPECTED RESULT
The clock and date are rendered using grayscale antialiasing.

Use PlasmaComponents labels for the re-usable clock component

This component is supposed to be used in Plasma UIs, not desktop UIs. So
it shouldn't be using QQC2 components.
