This new build r60820 has a problem with frames containing heavy javascript. I have a base of data that is published on the net with Instant Web Publishing from Filemaker. It uses java script to create and make editable the main table view. With this new webkit build after login the page becomes blank. I cleaned all cache, reset Webkit. Nothing works. Returning to the previous build resolves the issue.
It's going to be hard to fix this without additional information. Can you post an example on the Web? Is there anything logged to Web Inspector console, or to Mac OS X console? I looked through commits in this range, and I don't see any smoking gun. These two changes seem most suspicious: http://trac.webkit.org/changeset/60762 (JSC errors) http://trac.webkit.org/changeset/60813 (HTML5 parser changes that also affect common path) Gavin and Adam, can you take a look?
Might be a duplicate of bug 40292.
I'd be surprised if http://trac.webkit.org/changeset/60813 was the cause. The changes to the common code paths amounted to inlining methods. However, stranger things have happened.
