Chrome recently started this severe janky behavior. When I scroll ANY PAGE, the content is blank for a full second before Chrome renders the content. Even when I scroll back up to previously rendered content, it is blank for a full second before Chrome rerenders the content! It is super annoying!
What broke? And how do I fix it? Use the flags page to demonstrate the behavior: chrome://flags/
I'm running the latest Chrome version on the latest Beta Mac OS:
Chrome Version 108.0.5359.124 (Official Build) (arm64)
macOS Ventura 13.2 Beta(a)
I found a fix/workaround that restores smooth scrolling and everything is already rendered! Go to chrome://flags/ and disable "Threaded Scrolling." I haven't noticed any page performance degradation either.
