Yet I don't think Adrián's tweets are that heavy. I'd try with Epiphany tech preview as well, but currently it is utternly broken and unable to load any pages (I get "(epiphany:2): epiphany-WARNING **: 20:32:31.926: Web process crashed" spammed in the terminal when running it) *: it happens in any regular epiphany window (no need for app mode), including a regular private window. For testing's sake, it's easier / more standardized for me to just use a private navigation window for this. 1951549 1 kdwkleung 2023-04-27 02:08:51 -0700 Unable to reproduce in GNome Web 44.2/ WebKitGTK 2.40.1. Perhaps fixed already?
