Screenshot of Night Light settings page

SUMMARY
When playing games, I don't like having Night Light enabled; it can make some dark scenes too dark to see anything — I always forget to manually suspend it.

For example, Plasma 6.4 is now enabling do-not-disturb for fullscreen apps. This feature request is very similar, but for Night Light.

STEPS TO REPRODUCE
1. Not a bug

OBSERVED RESULT
Night Light doesn't suspend on fullscreen apps.

EXPECTED RESULT
Have a checkbox in the Night Light settings page; if it's enabled, night light will be suspended (with a reasonably fast transition) when the window in focus is in fullscreen mode. This should probably be disabled by default.

Maybe... though this somewhat conflates "fullscreen app" with "video game". There are plenty of cases where you'd want Night Light to continue working in full screen mode; basically everything that isn't an app or a video.

Would you instead prefer to blacklist specific apps? If so, that's already tracked with Bug 487304.

Yeah, that would work. Thanks.

Should I close this as a duplicate?

If that would work for you, then yes, let's!
