--- Comment #5 from rimbotede at hotmail.com ---
I've been told that downgrading to such old package versions (Fedora 18 times)
would be extremely troublesome. Especially that many components come into play.

I've requested assistance on Fedora devel mailing list with updated
troubleshooting info (pointing at Gnome as the culprit). Updated summary of the
regression I posted:

1. Introduced between Fedora 18 and Fedora 19 releases. Clean Fedora 18 showing
no performance problems, clean Fedora 19 being affected by the regression.
2. A system install (e.g. Fedora 19) affected by the regression shows no
performance problems under KDE. The difference in desktop animation smoothness
is striking. No need for telemetry.
3. A Gnome Shell developer (drago01) could not reproduce the bug on his Intel
GM45 system.
I've done some F18 vs F19 vs Arch benchmarking / Gnome vs LXDE using Xonotic in
windowed mode but the results were nowhere near as conclusive as #2.
