I found the cause!!!
It's the stupid Feedback hub. To fix the issue, go to
Privacy settings and then to
Diagnostics & feedback, from there, change:
1-
Feedback frequency from
Automatic (Recommended) to
Never.
2-
Diagnostic data from
Full to
Basic.
3-
Improve Inking & typing recognition,
Tailored Experience and
Diagnostic data viewer all to
Off.
Also, while you are at it, delete the diagnostic data by clicking on
Delete from the same settings page. (don't think it's necessary though).
4- And this is the most important thing to do: from
Start Menu, search for
Feedback hub and then right click on it and click
Uninstall. (don't worry, you can install it again from the Store should you ever want it again, but why would you?
😛
EDIT: Just uninstalling the Feedback hub app from the
Start Menu (without doing steps 1-3) does the trick but I would just still do all the steps to be sure.
Want to know how I found out? OK here's the story:
From
Search Everything app (https://www.voidtools.com/downloads/) I viewed all Partition C:\ files and sorted by
Date Modified and waited for the blink to happen, once it happened I quickly took a screenshot and at the exact moment, the last modified file was located at
%UserProfile%\AppData\Local\Packages\Microsoft.WindowsFeedbackHub_8wekyb3d8bbwe\TempState\DiagtrackClientBackgroundTaskOnTimer
There you can find that a new folder is created once every ~10-20 minutes (and that's the very exact frequency of the blink). Then I was sure it was the cause. So I went and did the steps above and the issue is gone for good now.
Why it started few weeks ago for me? because I went and updated all the Store apps manually ~2-3 weeks ago and the Feedback hub got updated, I never updated the Store apps and I always turn off automatic updating of them right after I install a fresh Windows 10. I believe it's the updated version of the Feedback hub that does this icon flickering.
@jonahwalton and
@Colif I am so eager to know if the steps above (especially step
4) will fix it for you guys as well.
