Alt+Shift+End Are you seeing anything at all? The intended appearance is mostly red and black with a "photo negative" appearance, just like a photographer's darkroom.

You can use Alt+Shift+Page Down to go to 800K.

Ah. Okay. CWM temporary. Intel x64, stock rom from asus, because still imposible to install other stock rom on asus device, their system is complicated. Ah anyway it's working when I change my color driver, I use default compositor, when I change it to Qualcomm or Tegra it will work only for the dark room mode, but not for the flux filter anyway. Something strange happened 😓😓. So would you debug it?

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:

@Adam-Michael-Sasine Make sure you have "automatically adjust brightness" in Display system preferences turned off. Other than that I don't know, but in an emergency you can run RedScreen for Mac OS. You have to quit f.lux first, otherwise exactly the same thing will happen! It can be a symptom of two different things trying to adjust the screen at the same time.

@Tungsten_smooth said: @Gentz Now you can open the magnifier and invert the colors (ctrl alt i). I think it's the APU not understanding the color inversion part. Yeah, something somewhere is definitely not allowing f.lux to work correctly. :/
