journalctl output

I am running the Fedora 25 Wayland Live system, but the bug is also
reproducible using other distros and Xorg.

When running a 3D app the screen hangs, but the rest of the system keeps
working fine.

I can reproduce it like this:
1) Boot a live system.
2) Launch firefox
3) Start a webgl app and run it for some time. It should hang after a while.

I attach the output of "dmesg" and that of "journalctl -b".
