Please provide a specific URL on which you see the problem. Please also indicate how you are scrolling - keyboard? mousewheel? scrollbar dragging? Also please go to about:support (not in safe mode) and let me know what it says under "Asynchronous Pan/Zoom" in the Graphics section. Thanks!

Thanks! Every url, including this one. Scrolling using mac touchpad gesture, two finger drag. Asynchronous Pan/Zoom wheel input enabled; scrollbar drag enabled; keyboard enabled

Can you check you get the same Asynchronous Pan/Zoom text in safe mode? If so the problem is likely one of your addons or preferences, since that's the main difference between safe mode and normal mode. I would suggest disabling addons one at a time until the problem goes away, which will help isolate the problematic add-on, if that's the problem.

Oh sorry you already said it still happens with addons disabked. Have you modified any preferences via about:config?

I have pasted the full text from about:support on both normal and safe mode into a gist here: https://gist.github.com/ibrokemypie/5985d14ad9082e6e128ed557296845d6 Immediately what stands out to me is that safe mode disables hardware acceleration and webgl

I just disabled gfx.webrender.enabled, and now everything is working smoothly. This also solved https://bugzilla.mozilla.org/show_bug.cgi?id=1391689 for me

Thanks for the update. Please note that webrender is still *very* experimental, and if you run into graphics/scrolling bugs the first thing you should check is if it still happens with webrender off. Any bugs that only happen with webrender should be filed in the webrender component.
