  • f.lux team

    temporary fix here:

    We are waiting on MSFT for the real fix.

  • Thank you, that got f.lux working again!

  • Thank you, I've been at a loss without f.lux!

  • Interesting side-effect of using the beta (at least with 4.94) on 19H1 (at least with 18317) is that when you're making a screenshot (the program doesn't seem to matter, but Snipping Tool is handy), at the moment when you're selecting the part of the screen that you want to capture, the color temperature of the screen drops way down until the capture is complete. And the captured image takes on that hue! I've never seen that before, and it doesn't happen with f.lux disabled.
