Unable to scroll via trackpad
I can no longer scroll via my MAC trackpad using Vivaldi 1.12.955.38 / MAC 10.13 (High Sierra) suggestions?
Removed a smooth scrolling extension, everything is fine now.
It is always good as a the first step to test with deactivated extensions.
So you can check if it is a Vivaldi or extension problem.
I understand it is resolved for you now after removing the interfering extension.
