Created attachment 393843 [details] build.log with -DENABLE_TOUCH_EVENTS=OFF I had this option set before trying 2.27.x along with others, I managed to get enough available CPU time to keep pocking at which option would make it fail. Attaching the build.log, recipe used (but with -DENABLE_TOUCH_EVENTS=OFF commented off) can be seen on <https://gitlab.com/lanodan/overlay/-/blob/beff1428d6e4ccf7f941b338afb84c848a574445/net-libs/webkit-gtk/webkit-gtk-2.28.0.ebuild>.
