Wonky brightness slider mess by restarting KWin
DESCRIPTION
I discovered this after needing to restart KWin for lag issues and then
brightness hotkeys stopped working (the shown slider got stuck at 90 or 85%),
and when I checked the applet it showed two brightness sliders despite my
laptop being single monitor with no external screens connected. One of those
sliders behaves normally-ish and the other is quite buggy. [screenshot]
STEPS TO REPRODUCE
1. Login (preferably on a single-monitor setup for accuracy)
2. Test brightness hotkeys, they should work normally
3. Restart kwin and wayland (I did with kwin_wayland --replace and plasmashell
--replace).
The "A new screen has been connected notification" will show up, which 1. is
wrong and 2. is the first symptom.
4. Test brightness hotkeys again. The brightness gets stuck at the same
percentage value again.
5. Open the applet; now you still see a single slider but brightness hotkeys
are broken anyway.
6. Restart KWin again and repeat from step 4. Now hotkeys still don't work and
you have duplicated sliders and neither do work correctly/behave consistently
(they start to flicker if you move them around).
OBSERVED RESULT
The previous slider mess described
EXPECTED RESULT
Sliders should work normally as they did before :\
SOFTWARE/OS VERSIONS

ADDITIONAL INFORMATION
