When I hover over a menu in Chrome (Version 21.0.1180.79) only (not all webkit) and then unhover a portion of the menu is ghosting (staying in place) until an element is adjusted in it’s place in which case the overlapped area goes away.
For example, on the page: http://www.georgianc.on.ca/student-success/ if you hover over ‘Co-op and Career’ (in chrome) and then unhover you should see the issue.
This question appears to be the same issue (I can’t tell for sure as the example was taken down) but I can’t find any ‘visibility’ rules that apply to the menu in question… need fresh eyes? css menu hover "hangs" in chrome & safari

For some reason, the problem appears to be fixed if you set
position: staticon#menu-item-197. I don’t know why, though, and it probably shouldn’t ghost in the first place – but at least it works!
