Video artifacts with f.lux v 4.47 in sunset/night mode in Windows 10



  • Re: Strange colors/blue-fringed mouse pointer on full-screen YouTube when f.lux is active

    I am referring to the previous article as it is quite old and was advised to start a new thread by your system.

    The video artifacts appear in videos, games, screenshots etc when in sunset/night mode, on Windows 10 creators update and beyond, as a Windows insider, I am now running the Fall Creators Update (version 1709, build 16299.15) and the artifacts still exist, interestingly enough they also appear using Windows 10 built-in Night Mode, but to a lesser extent, it is difficult to describe how they look visually in text but as mentioned in the referred to article above the effects are bright colour edge halo's to various background objects usually a bright magenta in colour but in a video say where there are smooth transitions from light to dark these will be edged with halo's.

    In fact, the easiest way to describe it is like running 24/32-bit colour in 16-bit mode if you remember years ago when there were only 16-bit colours available on most computers with the odd top end machine having a video card that supported 24/32-bit colour or TrueColor as it was referred to back in the day.

    I hope this will help to give some insight into the problem for your developers, for your reference, here is a brief spec list of my system :-
