When does it flicker? I am seeing lots of regressions in these insider builds.

Looks like everything is working a lot better now.

The main (release) build will work also, but this one should be more efficient.

But based on that trajectory (the build after when they said they fixed it actually does), I'd expect next week's 20H1 (post 18850) build to also have the fix.

I hadn't noticed that 18348 (Mar 1) had this in the release notes:

"If you use third party apps to adjust the color of your screen, we’ve made a fix with this build to address feedback that certain apps were no longer working. We’re continuing to investigate feedback in this space."

And today's 18850 has the same note.

Did you find 18348 still needed the workaround? I'm about to try 18850, so I don't know about it yet, but it should be in the same boat as 18348/18351.

Just to explain it a little better in case it matters, it's not that blacks are affected exactly, but black artifacts appear randomly over non-black areas. In this sense, you might say that it's whites being affected, or at least anything not black.

I know about some flashing like this in 1803/1809, due to the way the profiles are loaded/reset from Windows. Generally the bug we are working around in the shipping versions is that the system treats any device change (like a bluetooth headset or USB insert) as a "reset" to the color system, and so we have to race around trying to fix it. I don't know what is going on in this new version yet, but I am watching - guess we have another potential release later today.

The black "blocks" randomly flash in a portion of the window and then disappear.

It took me forever to realize that f.lux was doing it, since it's not a constant thing at all, though only since the workaround has been needed.

I just manually closed F.lux and reopened it and it turned on (PHEW)! So glad to have it back. Hope it's fixed in a new build soon.
