After upgrade to 8.3, cannot access any URL if using Safari, type anything in address bar came with blank content below, no prediction, hit GO button with no response, then Safari was like freeze, check log can see 100% CPU utilization error by Safari. I tried to reset network settings, clear safari data, with no luck. Restore to 8.2, issue is gone. Upgrade to 8.3, with no data restored, thing's fine. As soon as I restore with my old data, the issue is back. Very headache. Anyone has same problem?
