The Chromium Embedded Framework (CEF) project has it's own Issue Tracker, please report this issue there. CefSharp is just one of many wrappers around the Chromium Embedded Framework (CEF)

If you do find an existing issue that matches this one or create a new one then post a link here for others.

Closing this as upstream as changes/fixes need to be made in CEF.
