Problems after updating to Windows 10 May 2020 (version 2004)
-
Apparently Window 10 May 2020 Update (2004) introduced WDDM 2.7 (Windows Display Driver Model) and "should improve multi-monitor support" (you know, 2 steps forward, 1 step backwards... the more features you add, the more bugs comes along). So here are my suppositions on what might be going on:
1 - WDDM 2.7 breaks previous functionality intentionally and documented this.
2 - WDDM 2.7 breaks previous functionality intentionally and didn't document this.
3 - WDDM 2.7 breaks previous functionality unintentionally (a bug on Windows so not f.lux fault).
4 - Some internal component of Windows that manages multi-monitors wasn't upgraded properly to deal with WDDM 2.7. That would include the Windows Title rendering of windows (a bug on Windows so not f.lux fault).I am not a Windows developer so I might be totally wrong on this, just following a feeling on what could be the root of this.
According to an article "WDDM 2.7 in Windows 10 version 2004 requires Nvidia drivers 450.12, Intel driver 27.20.100.7859 and above." But Nvidia is only servicing 446.14 for my GTX 1060 so this might be a corner case while the new drives don't go mainstream? Don't know, just another wild guess.
-
@mfeinstein I checked the GeForce website with various graphics cards, and they all show 446.xx as the latest. I am on 1050 and I have 446.14 too. I guess we have to wait till 450.xx comes out.
-
We have issued two updates, and the most recent has a toggle (f.lux options) to use the "internal" setting.
Can you see if just updating helps, and if not, if toggling the setting helps?
-
@herf what do you mean by "use the "internal" setting"?
-
@herf I can't see any options saying anything about "internal" settings. I am using f.lux version 4.116.
Also I tried to simulate the 24hrs interval by clicking twice on the 24hrs graph and the problem I first reported persists, regions 2 and 3 of my first image have the same colors.
-
After a restart f.lux says it's on limited color mode and once I enable more colors and restart it works as it did before, thanks!
(I still can't see any toggles for internal settings though)
-
@mfeinstein I believe @herf is referring to the "Always use Windows internal color table" setting, see the screenshot below.
-
It will only appear if the feature is available at all - otherwise the checkbox would have no effect.
-
@lamchcl can't find this Tuning menu anywhere.
But so far things appear to be working just fine.
-
I can see it under "Options and Smart Lighting".
@herf I just got an update to version 4.117, but the What's New page apparently removed the v4.116, if it was a beta then it shouldn't be on the What's New page, and if it wasn't a beta than v4.116 shouldn't be removed, my 2 cents.
-
@mfeinstein thanks - yes all the notes since the previous version are there - but this readme is intended for normal releases.
We pulled all the May 2020 Windows people into the beta temporarily to get the bug fixes out, but that will be turned off as soon as it's stable. (i.e. as soon as possible)
