When an application is built with .net version 4.7, the paragraph dialog is clipped in the bottom.
.NET Framework 4.7, WPF replaces the algorithm that the Grid control uses to allocate space to *-columns. By default, apps that target versions of the .NET Framework starting with the .NET Framework 4.7 will use the new algorithm, while apps that target the .NET Framework 4.6.2 or earlier versions will use the old algorithm. To override the default, use the following configuration setting: <runtime> <AppContextSwitchOverrides value="Switch.System.Windows.Controls.Grid.StarDefinitionsCanExceedAvailableSpace=true" /> </runtime> https://msdn.microsoft.com/en-us/library/mt807865(v=vs.110).aspx
