So the disabled preferences are for the two programs I've set it to, neither of which are the programs it kept disabling for. These programs include: Chrome, calculator, Brave, Firefox, Discord, Steam, Windows Explorer, and notepad

This bug seems to fixed already. It's not reproducable for me at v4.111

Thanks @Paul-Harris - for some context, f.lux v4 avoids constantly looking for color changes and tries only to "fix" what other programs do in a few specific ways, so you're seeing what's expected, except that f.lux should definitely be detecting any new screen that makes your desktop bigger, so that's a bug. That list currently includes: plugging in a new device (which seems like it's not working here), returning from sleep, and switching apps (like alt-tab). When you plugin a device, does it look right for a bit and then reset later? Or does the tint instantly disappear?

Thanks all. Installing the newest Nvidia driver also fixed it for me.

@onotole f.lux actually modifies this setting for activation at sunset. Then I assume it sets the "dark theme" back to unchecked, once sunrise happens. It's probably enabled by default in f.lux, so look in the settings there first.

@oschlag Ah, sorry for making this duplicate thread then! Thanks for the link.

@Mango Thanks, that seems to work. Good to have the bug confirmed too.

The problem seems to be still existent. I am using a OnePlus One with CyanogenMod, Android 6. Only the standard color driver works for me, not Qualcomm or Tegra. After a few seconds it is not black background and red text but red blackground and black text... Please fix it :disappointed:
