Its on an intranet site we are developing so its difficult to give the example. But i can confirm that from closing my pc down on friday afternoon last week the problem wasnt there. Clearly chrome updated when i re-opened again on monday morning (22nd)

Please try to get a simplified repro case if you can. It's really hard to fix things where there's no repro case.
