Hello, I am hosting Wpf elements inside a WinForms form, using interop through the ElementHost class. When I resize the Wpf element using a Wpf Thumb control, I am getting a noticable flicker. During the drag of the Wpf Thumb control, I resize the transparant parent WinForm and this correctly resizes other Wpf elements docked to it. There are no visible WinForm items only Wpf that need to be displayed and I suspect that Wpf and Dx are rendering along with GDI+ for the ElementHost whose child is the Wpf UserControl that contains the displayable content? And this causes the horrible flicker. Is it possible to disable rendering at the ElementHost level, so that only Wpf renders? Or is it possible to sync the rendering of a frame in Dx when the content is ready to display. (similar to a double buffering technique that I know Dx does) Any help is greatly appreciated.
