Bug 1569881 added a workaround of flickering of Intel GPU. It was addressed by Windows update KB4512941.

https://support.microsoft.com/en-us/help/4512941/windows-10-update-kb4512941

From the following, it seems better just to remove the workaround.

  • To detect the fix, we could not use windows version number
  • The problem affects only to Windows version 1903(OS build 18362)
  • The fix could be applied by Windows update
  • Bug 1569881 fix regresses performance
