So this issue is happening when I have a single Chrome tab open (on this issue page) and nothing else. The usage does spike up to higher than 25% for a couple of seconds then back down to 10%-ish (one for Xorg and one for Gnome shell, so 20% on average). My laptop fans spin quite loudly too. I thought it might have been because I was trying a new GTK theme, but I went back to Yaru dark and I still see the same issue.
