Bug is still present in Plasma 5.20.2 
Affects me as I use gpu passthrough and frequently switch the display to a VM. When I switch back to host after sunset, night-mode has not been applied and has to be applied manually.

Still the issue as of 5.26.4.
Comment 3 Nate Graham 2025-08-01 22:33:29 UTC 
This has been working for me for quite some time now. Is anyone still able to reproduce it in Plasma 6.4 or later?
