Just to let you know updating sorted my problem right out. However... It has left me with a far more frustrating problem. Now somewhat randomly when I disable the f.lux (so "disable until sunrise") and then reduce the brightness of my screen using Alt+PgDn my screen return to full brightness and I can't work out why. If I then press Alt+PgDn again it dims to the previous level , rather than one less than normal. So i go from 82% brightness (the setting of my display), down to say 25% using Alt+PgDn, it then jumps back up to 82% and if I press Alt+PgDn it doesn't go to 76% (the setting one below 82%) but rather straight to 25%. The interval of the brightness jump seems to be random and it only ever increased brightness not decreases. I've completely uninstalled and re installed f.lux to try and fix it, no help. Honestly I'd rather go back to v4.55 as that issue was far less annoying!

Sorry to awaken this two year old thread... but i’m Actually trying to get flux to appear on a screen recording. I want to record a video the way it appears with the darkroom filter on, but it doesn’t appear when I attempt a screen capture. What is a good way to get this to appear? Thanks, Spencer
