Using Archlinux, Epiphany/Web 3.16 - webkit2gtk 2.8.3 - gtk 3.16
When I log into my https://fastmail.com account, the browser freezes and make the computer unusable. The processes seem to eat all the CPU.
To help debugging, I compiled the code found there: https://wiki.gnome.org/Projects/WebKitGtk/ProgrammingGuide/Tutorial replacing webkit.org with fastmail.com.
gcc -o browser main.c `pkg-config webkit2gtk-4.0 --cflags --libs`
It has the same behavior as epiphany, but gave me this output:
radeon: The kernel rejected CS, see dmesg for more information.
which I did, and dmesg shows:
[347915.271229] WebKitPluginPro: segfault at 0 ip 00007fcc44f31afb sp 00007fff84abe110 error 4 in libwebkit2gtk-4.0.so.37.6.6[7fcc44918000+214d000]

I don't think it's radeon related though, because it also freezes on my laptop with intel GPU.
Thanks for moving this here.
