I'm using CEF 3.2171.1902 and mouse context menu is misplaced. Top-left corner of menu should be placed in the click spot. Attaching screenshot 1.
I've also noticed an issue in cefclient. Mouse context menu UI is not the standard one used by OS. Attaching screenshot 2. Mouse context menu in all applications is the same as on screenshot 1. It is cefclient that is using a strange menu.
Running Windows 7 64bit with High DPI settings (Larger 150%).
