A couple of users have reported / shown me examples of record forms where embedded reports are not displaying in Chrome. It APPEARS that when the page is loading the reports flash on the screen in the correct spots, but once the page has loaded there is just a blank space where the embedded report would normally be. The blank space seems to take up the same amount of space on the form that the report(s) would normally take, there's just nothing there . . .
Have not been able to duplicate in IE or firefox as of yet.
I would first start off with submitting a ticket to the Chrome team to see what can be done to resolve. Also, since this issue appears to be specific to Chrome's latest update, you can try downloading previous versions where the issue did not occur: http://www.filehippo.com/download_google_chrome/history.
(The issue as others have reported does not show up in Firefox or IE, so it appears to be a Chrome specific problem)
