Build 21277 is out as an Optional Update

5. I hadn't given this much concern before this discussion.

On a bright note, if something is actually broken, it works in your favor of clear rather than stuck on blur.

That would be frustrating  :-)

@Johnny55, @Drew1903,

Just to confirm the different behavior I did an experiment myself.

I usually don't play with Hyper-V because MS wants yet a separate license even for testing the damn insider builds. 😜

Also Running on a Virtual machine is much slower that running on a real one.

Anyway I setup Hyper-V on one machine (MSI GT70-0NC host running 20H2 Build 19042.685) and did a clean install of 21277.1000 on a Virtual Machine guest. The behavior on Hyper-V is sure different than the behavior on a real machine, it looks like with Hyper-V, the VM guest is bypassing the policy and shows clear logon background regardless of the policy or the registry settings. 

The question I have now is:

Was this intentional or just a mistake, why is the Hyper-V guest not conforming to the policy and/or registry settings ?

The same clean install of 21277.1000 on a real machine behaves correctly according to the policy settings.

Hyper-V Clear background on logon regardless of the policy:

On my primary system right now so can't confirm exact number but was either 457.51 or 456.71 offered through Windows Update.  I had been running the 460.20 over the last few updates and that driver didn't allow me to change to higher refresh rate, the older one did.  I didn't try the newer one from Nvidia on my Insider one, but am running that version on my Primary system with no issues.  I will have to boot back to the Insider drive and try the 460.79 one.

edit - running 456.71 from Windows Update, was running 460.20 and was offered the older one as an optional driver "update"

edit 2 - Now running newest driver from Nvidia 460.79, am able to run my 240 Hz refresh rate with no issues.

@David Vair, 

Just F.Y.I.

There is a bug in Skype that was introduced with Nvidia Drivers 460.79 and 460.89 (Now with Hot Fix 460.97).

I could reproduce the problem consistently with my Dell XPS 8930 and Nvidia RTX 2060.

I had to go back to Driver 457.51 to eliminate the problem.

See my last post on this thread:

Yes, always glad when & if I don't have to see or look at it blurry.  When it was blurred I, of course, just put up with it.  Actually, now that I'm brought to thinking about it... it didn't pay attention to the settings then, either, which is why I just lived with it.

Then, one day... 😊

BUT

One BIG reason I didn't delve into it was there was a known inconsistency with it, for a while; from the developers, I mean.  They did change back and forth a bit with this one; at least that was my understanding

I have had this situation long before 21277.

1. Long ago I made my Win10 be NOT blurred.
2. My IBs have been blurred & focused, at various times/inconsistent. Prefer NOT blurred. It was set to Not configured, even though NOT blurred.
3. Quite some time ago, noticed the IB was NOT blurred, anymore. I had done nothing to change it.
4. Since this discussion realise the IB (NOW) stays NOT blurred regardless of how Group Policy is set.
5. I hadn't given this much concern before this discussion.

Cheers,

Drew
