    Latest information

    June 3
    We are updating 17134 and later users to 4.73.

    v4.73: has a workaround that seems to fix the issue
    v4.72: tried to look for the problem and fix it as quickly as possible

    https://justgetflux.com/flux-setup4.exe has the latest version, and we are posting new builds to the main page also.

    Background

    Windows 1803 (build 17134, the April 2018 update) has a bug that resets color adapter settings every time a driver is added to the system. Bluetooth headphones, network adapters, etc. all do this.

    Some people who have devices attach and re-attach frequently have been experiencing f.lux flashing or disabling unexpectedly.



  • Using 4.73 on Win10 1803 and still experience f.lux getting unresponsive after a while. It happens constantly. The only way to stop f.lux is by killing the job in task manager. But after a while, screen colours revert to standard and f.lux is again unresponsive.

    It is possible that the NVIDIA driver has an available update.

    Also, do you happen to know if the same issue occurs with the Displaylink monitors unplugged?



  • It's the latest nVidia-driver.
    I'll try running it without Displaylink dock and return.



  • Same here.
    Win 10 1803 and 4.73

    Lenovo 510s.
    Intel HD Graphics 620

    The constant flashing seems to occur more after unplugging 2nd monitor.

    @rtbbj can you post your driver information too? This is presumably with Displaylink (USB) adapter?



  • I've now run without Displaylink dock for 40 min and still no crash. It does look like a problem with Displaylink. A little weird as Displaylink is recommending using f.lux instead of standard Windows (https://www.displaylink.org/forum/showthread.php?t=65442&highlight=night+light).

    I am not seeing any new bugs due to Displaylink when testing, so maybe it isn't that.

    Our crash logs are very good for this version (maybe some are not getting through) - but there is one for the notifiers. Do you have any apps disabled/etc. that would show a notifier?



  • I don't understand. Which notifiers?



  • I believe I am having a similar problem to @hba66 and @RtBBJ . Flux v4 randomly freezes and becomes unresponsive after 20-40 minutes of use.

    I posted it about in a separate topic (https://forum.justgetflux.com/topic/6409/latest-flux-version-becoming-unresponsive-after-about-20-40-minutes-consistently-and-stopping-color-effects). Driver Info output is located there as well.

    I had no issues with the same setup for Flux v3 - issues started immediately after upgrading to v4.



  • 4.74 seems to have fixed the problem with crashes when connected to Displaylink. Great! Thanks!



  • When the most recent update came out, I have Windows 10, I have a strobe effect thing happening just as the evening change happens.



  • @deanawat I am also having the same issue. I am using Windows 10 on a laptop with nothing else plugged in except a mouse. I do most of my computer time at night when the filter is most needed. I don't want to have to disable it but the strobe effect is making me sick.


  • f.lux team

    Okay this is likely due to Windows Night Light.

    We pushed 4.75 which might fix it:
