SUMMARY When I activate the second monitor via the monitor widget, the monitor often turns on blue light. To get it back to diurnal (AM) temperature, I have to go into the night color settings and change the daytime color temperature STEPS TO REPRODUCE 1. I activate the second monitor (on the left) via the Plasma panel widget 2. The color of the screen changes temperature, it switches to that of the night even if it is not night 3. To get it back to normal, I have to go into the night color settings and change the diurnal color temperature EXPECTED RESULT When I activate the second monitor, it doesn't change temperature System info: Operating System: Arch Linux KDE Plasma Version: 5.26.5 KDE Frameworks Version: 5.101.0 Qt Version: 5.15.8 Kernel Version: 6.1.4-arch1-1 (64-bit) Graphics Platform: X11 Processors: 12 × AMD Ryzen 5 5600G with Radeon Graphics Graphics Processor: AMD Radeon Graphics ADDITIONAL INFORMATION This has been happening to me since the option was added to change the diurnal color temperature as well Currently my settings are: sunset and sunrise at current location (Italy) Diurnal Color Temperature: Cold (No filter) Night color temperature: 3.100k
Same issue as Bug 453374; see the explanation there. *** This bug has been marked as a duplicate of bug 453374 ***
Oops, sorry, that message was intended for a different bug report.
I have additional information: This happens more often when I turn on the second monitor the first time after turning on the computer I also have a video that I uploaded to Youtube. I couldn't upload it here because the file is 19mb and the limit here is 4mb, sorry if I can't post links https://www.youtube.com/watch?v=wH5bCclUa9s
Can you run qdbus org.kde.KWin /ColorCorrect org.freedesktop.DBus.Properties.GetAll org.kde.kwin.ColorCorrect && echo "currentTime: $(date +%s)" before and after connecting second monitor?

All right. It might take me a day or two to post this because, I don't know why, this thing doesn't happen every time I activate the monitor

No.. > After: > > available: true > currentTemperature: 6500 > ... > targetTemperature: 6500 That's when the screen is red, right?

Yes. I noticed another thing, the screen turns red when I activate the second monitor in the morning, if I activate it now the problem is not there. Tomorrow morning (Italian time) I'll try again to confirm. Now here it's 3:29 so that's not the problem

How can I give more information?
Can confirm this bug. Selecting "Extend to left/right" screen layout option turns on blue light on primary monitor if it was off, or turns it off if it already was on. Holding mouse button pressed on "Night color temperature" slider in order to preview temperature inside System Settings fixes issue.
