Hello everyone!

I need help = with dissecting the performance regression i.e. identifying the faulty comp= onent. It's far beyond my skills to do it on my own. I can provide system i= nformation and command line outputs but I couldn't e.g. downgrade xserver t= o a specific version or do a selective update of only Gnome Shell=2C only g= raphics driver etc.

Regression summ= ary:

1. Introduced between Fedora 18 and Fedora 19 releases. Clea= n Fedora 18 showing no performance problems=2C clean Fedora 19 being affect= ed by the regression.

2. A system install (e.g. Fedora 19) affect= ed by the regression shows no performance problems under KDE. The differenc= e in desktop animation smoothness is striking. No need for telemetry.

3. A Gnome Shell developer (drago01) could not reproduce the bug on hi= s Intel GM45 system.

I've done some F18 vs F19 vs = Arch benchmarking / Gnome vs LXDE using Xonotic in windowed mode but the re= sults were nowhere near as conclusive as #2.

I'd r= eally appreciate a thorough assistance with this issue.

Regards=2C
