Description mira.jary 2023-02-25 22:24:27 UTC
SUMMARY
When I plug into my laptop any external monitor while night color is active, the yellow filter suddenly gets applied only on the external monitor - it completely disappears from my internal screen. 


STEPS TO REPRODUCE
1. Turn on night color
2. Plug in second monitor
3. Observe

OBSERVED RESULT
Night color filter gets applied on all of the active screens.

EXPECTED RESULT
Filter gets applied only on the external screen. Cannot confirm if only on one or all of them, as my laptop has only one HDMI port.

Cannot reproduce with Plasma 5.27.2 on Wayland with my external HDMI screen. Are you using X11? If so can you try on Wayland?

Same case here, but filter was applied only for internal (built-in) screen only. Disabling HDR for external screen makes it turn off, turn on and everything works, but without HDR.

I can't trigger this on git master, neither with HDR enabled or disabled on the external screen

My settings.
Comment 8 Lach Sławomir 2024-02-22 13:02:11 UTC
I do not have git master, sorry.

Can you check one more thing? When I press Print Screen button, then external screen changes colors for moment.
I send also screenshot with settings page.
Comment 9 Lach Sławomir 2024-02-23 16:36:37 UTC
My Plasma6 got updated today. Night color working on external screen, thanks. Sorry for reopening issue. @mira.jary@gmail.com  can you update plasma and re-check, so somebody could close this issue?
Comment 10 Nate Graham 2024-02-23 16:42:40 UTC
Cool, thanks for checking on this!
Comment 11 Lach Sławomir 2024-02-23 16:44:51 UTC
Sorry Nate. Currently main monitor probably have Night Light disabled. I will wait until colors changes, but external monitor's colors are altered. On main screen colors are not altered. Just like in  mira.jary@gmail.com
Comment 12 Lach Sławomir 2024-02-23 17:36:23 UTC
Ok. Now, I see main monitor is darker. When disabling night-color both monitors are more bright. I see external screen gets more red colors, cause HDR.
Comment 13 Zamundaaa 2024-02-25 14:04:58 UTC
That would explain it - there was a difference between night light with HDR and without before. I did fix that already though. If you still see this with the 6.0 release anyways, just reopen this
