f.lux turns on/off when some windows are on different monitors

  • Since the last update (4.84), I've been getting a weird flicker where f.lux will turn on/off depending on if particular windows are active and (most confusingly) which of my three monitors that window is shown on.

    Sometimes, f.lux will pause when I open the print dialog in Adobe Acrobat Pro and have the dialog on the first or third monitor (f.lux unpauses when dialog is dragged to the 2nd monitor).

    Any guesses?

    My driver info is below and I'm on Windows 7.

  • Hm. It looks like maybe I had "disable on full screen windows" checked. Not sure why it was doing what it was doing, but unchecking that seemed to make it stay on consistently.
