[vtkusers] VTK and MFC access violation

Hi vtk-users,

We have an MFC application which contains a vtk-window (vtk 6.1). The application runs fine in different versions (32-/64-bit) on Windows 7, 8 and 10. However, there is an access violation with Windows 10 using a 64-bit Unicode build when the tab, in which the window is situated, is activated.

This is the code from vtkWin32OpenGLRenderWindow::SetSize(int x, int y) that we manage to debug into before the access violation occurs somewhere in the system-dlls:
    else if (this->Mapped)
      if (!resizing)
        resizing = 1;

        if (this->ParentId)
                       x, y, SWP_NOMOVE | SWP_NOZORDER);

The call-stack is attached as a .png

I know, this is a vague description. Nevertheless... any hints or guesses what could be going wrong here?
