Created attachment 366652 [details] Test Case In an HTML frameset, when the content of one frame is large enough for a scollbar to appear, scrolling that content causes a larger area of the screen than the frame concerned to be scrolled, this overwriting adjacent frames. 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

After some further testing it seems this bug is also wayland specific. It does not occur when starting ephiphany with GDK_BACKEND=x11
