Just upgraded to cef 3.1750.1619 and I'm seeing an issue with combobox elements (html select tag: http://www.w3schools.com/TAGS/tag_select.asp ).
When you click the combobox element it displays a drop down menu of choices. But the menu always seems to appear at the offset position of where the CEF window was first positioned. If you move the CEF window and click the combobox element, the menu no longer lines up with the html element.
This is reproducible with cef 3.1750.1619 cefclient, in visual studio 2012 with, CEF_ENABLE_SANDBOX=0.
See the attached picture for an example of the problem.
