Description John Tsombakos 2017-03-29 03:46:08 PDT
Latest version of Safari Tech Preview (Release 26 (Safari 10.2, WebKit 12604.1.12)) seems to beachball constantly.

Most noticeable on Facebook.com, load the site, try to scroll and it freezes with a beachball.

I tried to catch a sample, but couldn't.

I can reproduce in STP 26 but not with the latest WebKit so this may have been fixed already.

This progressed at https://trac.webkit.org/changeset/214333/, so likely caused by https://trac.webkit.org/changeset/213712
