Fullscreen WPF app crashes when connected via TeamViewer

问题

I've created a WPF app which works pretty stable. But there is one issue I'm not able to solve.

When I connect via TeamViewer (version 11) to the tablet on which my WPF app is running (in fullscreen mode), the app crashes. Same happens when I end the remote connection.

I got following exception:

System.ComponentModel.Win32Exception (0x80004005): Cannot create a file when that file already exists
at MS.Win32.UnsafeNativeMethods.GetWindowText(HandleRef hWnd, StringBuilder lpString, Int32 nMaxCount)
at System.Windows.Automation.Peers.WindowAutomationPeer.GetNameCore()
at System.Windows.Automation.Peers.AutomationPeer.UpdateSubtree()
at System.Windows.ContextLayoutManager.fireAutomationEvents()
at System.Windows.ContextLayoutManager.UpdateLayout()
at System.Windows.ContextLayoutManager.UpdateLayoutCallback(Object arg)

at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs)
at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Int32 numArgs, Delegate catchHandler)

I assume that the problem is somewhere in my code and is not a fault of TeamViewer. I was already searching for the GetWindowText() method without success. The only thread here on StackOverFlow which refers to the same exception couldn't help me either.

Hopefully someone can give me some reasons why this exception could occur.
