Problem with "Classic f.lux" setting

  • When bringing the UI in front and using "Classic f.lux", the CPU usage goes permanently to 20-25%. I also noticed that the last word of "The sun is up. Light is making your body later." is constantly switching between later/earlier.

    This does not occur when f.lux is in the tray and the UI is not visible. It also doesn't seem to occur with the UI visible and the other settings ("Recommended colors" etc. - haven't tested them all)

    By the way, is "Light is making your body later/earlier" a typo or not? Because I can't figure out what it's supposed to mean. :)

    W10 Pro 1803 x64, f.lux 4.84 - using the latest available driver from laptop manufacturer because the latest Intel 'generic' driver causes problems. Haven't tested the latest Intel driver against this f.lux issue.

  • Looks like it's a clash with Actual Window Manager. Adding f.lux to its exclusions solves the problem.
