I am using the C# WPF UI reference implementation for handwritten math recognition.
Steps to reproduce:
1. Clone the WPF example repository
2. Change the PART_TYPE in MainWindow.xaml.cs of the GetStarted project to "Math"
3. Compile and run the GetStarted project
4. Draw a single dot
5. Resize the window
6. The error occurs at line 232 of EditorUserControl.xaml.cs
Dear YS Lin,

I was indeed able to reproduce easily.
At present, we cannot commit when this crash will be solved.
