F.lux not working on monitor connected with USB adapter ( Fresco Logic drivers to be precise )

[randomfluxuser]

I don't know why flux isn't working on my current pc as it used to work on my previous pc on which I installed the same usb
adpater drivers, and used the same usb to hdmi adapter.

This adapter to be precise - https://www.amazon.com/Converter-Adapter-Windows-Computer-Firestick/dp/B07XYQN8BK/ref=sr_1_22?keywords=raycue+usb+to+hdmi+adapter&qid=1574252856&sr=8-22

These drivers to be precise - http://www.raycue.com/wp-content/uploads/2018/down/FL2000-2.1.34054.0.exe

Our ability to see color calibration failures broke in the May Windows update. Can you post f.lux options > driver info?

Same problem here - last days Windows 10 Version 1903 came in, and since then f.lux doesn't work on this monitor.
