Yes, I think it makes sense for a web browser to always have the AC enabled, because more and more websites simply don't work without it. But I agree that other applications don't really need it, maybe evo could enable it for email rendering, but definitely not for the composer, for example. The AC mode requires a lot more memory, is slower to start, and makes us depend on graphics drivers . . . So, yes, I'm in favor of keeping the non AC mode and allow applications to disable AC. > [0] - https://bugzilla.gnome.org/show_bug.cgi?id=774067 > > Tom > _______________________________________________ > webkit-gtk mailing list > webkit-gtk@lists.webkit.org > https://lists.webkit.org/mailman/listinfo/webkit-gtk -- Carlos Garcia Campos http://pgp.rediris.es:11371/pks/lookup?op=get&search=0xF3D322D0EC4582C3
