PropertyGrid is not displayed properly with .NET 5
See the question and my original answer on StackOverflowThis is a (huge) regression with .NET 5.0.4. See here:
"The default value is not displayed in the correct position after setting SelectedObject property for PropertyGird control"
https://github.com/dotnet/winforms/issues/4593
It will be fixed in 5.0.5.
