wacks keyboard RGB
Classification: Plasma
Product: plasmashell
Version First 6.7.1
Reported In:
Platform: CachyOS
OS: Linux
Status: REPORTED

DESCRIPTION
If I make another display the primary display, or I disable or enable a
display, after the first or so tries the RGB settings on my keyboard will get
wacked. (Color changes to blue and brightess is set to level 8 from a lower
setting.)
Keyboard is Keychron V3.
STEPS TO REPRODUCE
1. Change primary display to another display, or disable or enable a display
that is enabled/disabled respectively.
2. Do this one or more times. In my case it seems to happen consistently after
one try.
OBSERVED RESULT
Keyboard RGB color changes from reddish-white and level 6 brightness to
blueish-white and level 8 brightess.
EXPECTED RESULT
Keyboard RGB color and brightness level are unaffected.
