Comment 7 for bug 1183269

On my Ivy Bridge system, the dash now opens very slowly. Window and viewport switching are also glacially slow. A few other upgrades, like the kernel, arrived at the same time. But with pablomme's report, too, it seems more likely to be this.

Specifically it's Ivy Bridge GT2, aka HD 4500.

I'll try to grab the older packages, and downgrade mesa, to confirm.

Thanks.
