Hi im using the System.Window.Window Base class with a BlockText & a Border to create a tooltip like window.
The issue is that at a certain width that black box width 2 lines appears. Any way to get rid of it? Im not sure if this is connected to windows itself.
Thanks a lot

    Hello @Michael Six ,

    Welcome to Microsoft Q&A forum.

    I believe that you got this issue when you were debugging your project in Visual Studio.  

    Actually, this is a feature(XAML Hot Reload) of Visual Studio, and it is enabled by default in VS 2022 and later versions. You can disable it by selecting Debug > Options > Debugging > XAML Hot Reload > uncheck "Enable XAML Hot Reload" or uncheck other options for specific project types.

    Please check this document: Verify that XAML Hot Reload is enabled for more details.
