Windows 10 April 2018 Update issues



  • 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.



  • Okay this is likely due to Windows Night Light.

    We pushed 4.75 which might fix it:

  • @herf I can confirm that the issues that @deanawat and @danaandpete were facing are actually resolved in the latest update that 4.75 Thanks team!



  • Windows 10 1803 has been available to download since April and has been pushed out by Microsoft since May.

    Speedy adoption could be a sign the update is being welcomed by Windows 10 users, which might be true if it weren't for all the problems they have been facing.



  • I'm not able to install version 4. I'm getting a "Windows cannot access the specified device, path, or file" message. I've tried both the "flux-setup.exe" and the "flux-setup4.exe".

    I've also tried the version 3 install and it worked (from the same download location on my PC.)

    Any suggestions?



  • @baritonejp Do you have antivirus?



  • @herf Yes, I do.
    Remember that version 3 installed without any issues.



  • @baritonejp yes, many programs are whitelisted by AV companies by hand (especially old ones), so anytime we ship a new version, there is a risk that it is accidentally flagged.

    Could you could post information about which AV you have, and if f.lux installs properly when it is disabled?



  • @haanuman rel 4.76 still strobing.



  • I am also experiencing strobing with the latest nVidia drivers on both Windows 10 (build 17672) and Windows 8.1.

    Both PCs use a GTX 970 display adapter.



  • Just wanted to mention I am also seeing the strobe affect on 4.76 . Not quite sure what triggers it. It might be happening when a color change occurs?
    I usually go to the icon and settings and just toy with things a bit and eventually something I do (or maybe randomly) stops it?
    I have a GTX 1060 video card with driver version 391.35 .
    Displayport.
    I just went and turned off the DCI or whatever it was I saw mentioned elsewhere (in my monitor settings). monitor is HP Omen 32" 2560x1440.
    Hope that helps....



  • Continue to see the strobe as well. Very frustrating, especially since I donated money to flux. Hope this gets fixed soon so I don't have to continue to disable it.
