For example, I load
https://kotlinlang.org/docs/reference/multiplatform.html
And then I can’t scroll using my mouse wheel.
Very aggravating.
OS X, Google Chrome latest
Version 66.0.3359.139 (Official Build) (64-bit)
Repro after a cache flush and computer restart.
Can’t reproduce on Chrome latest on windows.
I’m having the same issue on Chrome version 66.0.3359.181 also on OS X 10.13.4
Maybe we have some extension that interacts with the site poorly? Are you on a corporate laptop?
I have the same issues for some time. I’ve tried on Chrome (no scrolling) but Safari & Firefox work. Any other site seems to be OK except kotlinlang,org
If that helps, I see the following in browser’s console:
Navigated to https://kotlinlang.org/docs/reference/keyword-reference.html
[Violation] Forced reflow while executing JavaScript took 31ms
keyword-reference.html:1 The SSL certificate used to load resources from https://data.services.jetbrains.com will be distrusted in M70. Once distrusted, users will be prevented from loading these resources. See Google Online Security Blog: Distrust of the Symantec PKI: Immediate action needed by site operators for more information.
Scrolling with the keyboard doesn’t work either. The only possible way to scroll is to use the scrollbar. Chrome 67.0.3396.87, Windows 7 x64.
It is working now, yay! Someone fixed something somewhere.
