In my case the workaround was to take the stylesheet (its was a typekit one for me) and make a local copy of it for my backoffice, and then reference that - everything then started working again. it can be similar if you are using google fonts too.

Hi
I ran in to a similar problem the other day, it is likely because you are including an external stylesheet somewhere in your back office in umbraco.
See: http://issues.umbraco.org/issue/U4-10936
There has been a change in Chrome 64 for security reasons - and this changes the access scripts have to certain elements of a style-sheet when it is loaded from an external source. (see https://chromium.googlesource.com/chromium/src/+/a4ebe08c91e29140e700c7bae9b94f27a786d1ca)

Legend. I would never have worked this out. It's a pain in the ass though.
