CefSharp WPF control crashes when interacting with HTML drop down lists (HTML select tag) #41

CefSharp WPF control crashes when interacting with HTML drop down lists (HTML select tag)

The issue can be re-producible with CefSharp.WinForms.Example.exe

Steps to re-produce:

  1. Launch CefSharp.WinForms.Example.exe
  2. Browse the attached 'dropdown-lists.html' file OR you can browse any website that has form with drop down select list, for example http://www.w3schools.com/tags/tryit.asp?filename=tryhtml_select
    1. Try repeatedly click on the drop down menu to display the popup
  3. You can also notice artifacts while rendering the popup

  4. It crashes with the following exception:

    System.AccessViolationException was unhandled Message=Attempted to read or write protected memory. This is often an indication that other memory is corrupt. Source=CefSharp.Wpf StackTrace: at memcpy(Void* , Void* , UInt32 ) at CefSharp.Wpf.WebView.SetBuffer(Int32* currentWidth, Int32* currentHeight, Int32 width, Int32 height, Void* fileMappingHandle, Void* backBufferHandle, InteropBitmap* ibitmap, ActionHandler paintDelegate, Void* buffer) at CefSharp.Wpf.WebView.SetPopupBuffer(Int32 width, Int32 height, Void* buffer) at CefSharp.RenderClientAdapter.OnPaint(RenderClientAdapter* , CefRefPtr* browser, cef_paint_element_type_t type, vector<CefRect\,std::allocator >* dirtyRects, Void* buffer)

Note: I am not experiencing this problem with CefSharp.WinForms control. It is working fine with the WinForms control.
