I did a quick search, and couldn't find anything that seemed to refer to this.
On certain websites, I can't scroll at all, as of this morning. No updates installed, tried doing a restart, and that didn't help. Example website: http://www.bikeradar.com

I'm on a 2012 Retina MacBook Pro, running OSX 10.12.6 with the latest update (which installed about a week ago)

Cheers,

Hugh
 
Alas, just questions... Perhaps to spark an idea or prompt others who really do know...

1. Can you scroll in other browsers or is Safari the only place you're having problems?
2. Do you have third party scroll helpers such as Smart Scroll installed? Or scroll helpers in Safari/Extensions?
3. Does the problem persist in Safe Boot?
4. Have you tried connecting an external mouse?
5. You mentioned "restarting", but have you done a shutdown and then rebooting?

Sorry if my help is not.
 
1. Just safari, and just certain pages
2. no scroll helpers installed
3. yes
4. yes, same problem
5. yes. same problem

Thanks for the suggestions though

Cheers,

Hugh
 
At this point, if it were moi, I would reinstalled the OS 10.12.6 "Combo" updater. It can't (shouldn't) hurt and reinstalling the combo updater is known to fix a myriad of ills.
 
Longtime reader of Bikeradar here. Yes, same issues going back ages with that web site, another is williams-sonoma.com. Those two sites have something going on in their structure that prevents them from working properly in Safari (I've tried the Tech Preview as well).

The only "fix" that I have found is to use the "Develop Menu>Disable Extensions" Command OR disable any ad-blocking extensions. Both of those sites are making calls to external services via javascript and I see the calls timing out.

I'm trying out the Firefox Nightly alpha (which has a built-in ad-blocker), and that browser exhibits identical behavior - but the current version of FF works like Chrome/Opera/Vivaldi. My workaround for each site's "quirks" is I've started using epichrome (which permits Chrome extensions) and I also use Fluid. That's all I've got…
 
Interesting - this behaviour seems to have turned up overnight - I haven't seen it before, and it suddenly started happening, even with my adblocker disabled.

I always used to use chrome, but I found the battery life/processor usage a deal breaker. Maybe I'll have to give firefox a go and see how that hits performance.
