  • .NET Core Version: (e.g. 3.0 Preview1, or daily build number, use dotnet --info) 3.0
  • Windows version: (winver) 1803+ (PMAv2 needed)
  • Does the bug reproduce also in WPF for .NET Framework 4.8?: Yes
  • Is this bug related specifically to tooling in Visual Studio (e.g. XAML Designer, Code editing, etc...)? no

Problem description:
[Port of a bugfix in the .NET 4.8 servicing pipeline.]

  1. Have 200% primary, 100% secondary
  2. Launch repro proj exe on primary
  3. Focus the textbox and see the caret blinking
  4. Move it to secondary

Actual behavior:
The caret disappears, but can still type in the textbox

Expected behavior:
The caret doesn't disappear.

Minimal repro:
[Available in .NETFx bug] It's just a WPF app with a TextBox, manifested to request PerMonitorAwareV2.
