I've been running into this UI issue on Windows 10 where when I get a notification through an app (especially Slack or Outlook), the icon glows orange to indicate it, but it never goes back to normal. The icon just stays orange unless I kill the app and relaunch it.

Is this a setting for some reason or a bug?

Windows 10 Pro
Version 1607
OS Build 14393.51

Eventually I found a solution to this problem, so for anyone who comes across this:

My solution was to change the blink rate of the keyboard caret in my Windows settings to something greater than zero.

Control Panel > Keyboard > Cursor blink rate: set to something greater than "None"

    @NicolasMartel Yep, I was trying to go for a block-style caret that didn't blink, apparently that property of the caret is tied to the notification animations some how? Bizarre Aug 15, 2017 at 20:39

  • Still happens in Windows 10 20H2. Never seen a weirder bug.

  • Worked a charm on my Windows 10 machine. Had to reboot though before it took effect.

  • Can it be that the flashing speed is bound to this rate? And that in case of "None", it unintentionally gets stuck forever? I've certainly seen stupid stuff....
