I attach some very small example files that demonstrate the problem and some screenshots. To reproduce unpack test case files into a directory, open frameset.html and scroll the right hand frames with the scrollbar. This came to light in epihpany, the GNOME web browser, where I initially reported it as https://gitlab.gnome.org/GNOME/epiphany/issues/710 1523980 1 stevenfosdick 2019-04-03 15:15:53 -0700 After some further testing it seems this bug is also wayland specific.
