journalctl with drm.debug=14

I am running Fedora 24 on Dell Inspiron 6400 a 32-bit CPU with Intel
Corporation Mobile 945GM/GMS graphics from GM installation media with 4.5.5
kernel.

After login to GNOME Shell/X11 the gnome-shell process takes 50-100 % of CPU,
rendering is slow. If I run `xrandr --output TV1 --off` as suggested here:
<a href="https://bugzilla.redhat.com/show_bug.cgi?id=1350133">https://bugzilla.redhat.com/show_bug.cgi?id=1350133</a> the CPU utilisation drops
but rendering a 720p video on YouTube in Firefox is impossible, frames are
dropped CPU utilisation spikes to 180 % for firefox process. If I run a 144p
video, it renders fine but CPU utilisation is at 70 %.

kernel-4.5.5-300.fc24.i686
xorg-x11-server-Xorg-1.18.3-2.fc24.i686

Graphics used to be OK on Fedora 22 with all updates (a 4.4.14 kernel).
