"Disable until sunrise" disables until midnight only.
My problem is simple. For example, at 22:45, I click on "disable until sunrise" so I can work on my color-sensitive work whole night. At exactly 00:00, it goes back to yellow. My location is correctly set to the city I live, double checked, and the local time is set correctly. "Classic f.lux" is selected.
I took a sucky video: https://www.youtube.com/watch?v=C05X8e9al7k
It has about 15 seconds of dead wait in the middle until the clock turns 00:00.
I didn't mess with my computer time to show you the problem. I actually waited until 23:59, which is about 10 minutes in real life for me before I posted this thread here.
will check it out
I am having this same problem Harzem, thank you for highlighting it to the Flux team! At midnight it resets and you have to click it again.
