f.lux instantly disables (it ignores the transition setting) when I access and navigate in System and Ease of Access settings in Windows 10 (build 19042.1237) until I focus on the desktop or another window.

Thanks - yes this is a known issue due to Windows - but happens usually only the first time. Also on some machines there is a workaround to use the Windows internal color settings. See this note:

Thanks, enabling "Always use Windows internal color table" fixed the problem. I have not otherwise noticed a difference. Are there disadvantages to enabling that setting? Also, do you know if Microsoft is aware of the problem?
