[Comment 1 Rafał Mużyło 2012-04-14 10:56:12 UTC]

Well, it's just a guess, but the fix is most likely either in webkit 1.8 or in the successor of epiphany (as it was renamed in gnome 3.4, IIRC).
gtk+ upstream decided to change the way scrolling is handled.

[Comment 2 Alexander E. Patrakov 2012-04-14 12:13:05 UTC]

Fixed by upgrading to net-libs/webkit-gtk-1.8.0-r300 that was in gnome overlay

[Comment 3 Alexandre Rostovtsev (RETIRED) 2012-04-14 18:17:48 UTC]

This is fixed by webkit-gtk-1.8.0-r300 and epiphany-3.4.0.1 which were added to portage yesterday.
