f.lux's screen effects turn off and on when I press alt+shift
Earlier today I was playing Overwatch on my PC, and sometimes when I would press alt+shift to check my web browser or something, my monitor screen would flash to how it looks when f.lux isn't being used (all bluish colored), and then switch back to normal. The switch only lasts a second or two. Not sure if this is an issue with f.lux or an issue with my PC? It just started today. Not really a major issue, but slightly annoying.
Is anyone else having this minor issue?
P.S. Great job f.lux team! This is my first time posting but I've been using f.lux for well over a year now and it's great.
