Created attachment 124860 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: https://bugzilla.redhat.com/show_bug.cgi?id=1350133 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 %.

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