Safari 14 stutters when scrolling

My late 2013 iMac was just upgraded with Safari 14. I find that when scrolling the screen seems to "stutter" This wasn't happening before. Also the tab titles are small and hard to read

the issue was present on another user’s account, but when I logged out of that and restarted a day later. The issue was resolved for all users including the dark band that had appeared across tab titles. All is well. I only wish I could have found what caused the issue. Thanks for the magic wand you sent along.

Hi BobL14,


Thanks for using Apple Support Communities. We understand Safari seems to act unexpectedly when scrolling. We’re happy to help.


First, restart in safe mode to see if that helps:


How to use safe mode on your Mac


Then, reset the PRAM / NVRAM on your Mac:


Reset NVRAM or PRAM on your Mac


Should the issue persist, test to see if it’s present in a different user account:


Set up users, guests, and groups on Mac


Let us know the results.


Take care.
