protected override void OnSourceInitialized(EventArgs e)
            base.OnSourceInitialized(e);
            HwndSource source = PresentationSource.FromVisual(this) as HwndSource;
            if (source != null)
                source.CompositionTarget.RenderMode = RenderMode.SoftwareOnly;
Does this problem also occur in the CEF Sample Application

NO, only occur in CefSharp.WPF.

Thanks for the workaround 👍 Have you reported the issue with the WPF team?
Making this as known-issue.
As this doesn't appear to be anything actionable from a CefSharp point of view I'm going to close this.
