Initial High CPU Usage and high disk write rate
If I just run epiphany and open for example https://example.com, and let it idle, I get high CPU-Usage (~12%) and a lot of disk writes (10-30 Mbit/s).
After around 1.2GB are written (~60s), the CPU-load on idle is at around 2-3%
I use the GNOME-nightly flatpak version, fedora 35, Web: 42.beta-really-7-g09d2249a+, WebKitGTK 2.35.3
