Hi, upgrading the xf86-video-intel from release 2.21.12 to 2.21.14 the gnome3 "exposé-like" effect (shows all the windows), it's not very good, with slow (jerkily) animation. Returning to 2.21.12 it's really fluid again. BTW: really thanks for creating the ebuilds just few days after the release :) Reproducible: Always

Can you try upgrading to a newer kernel? We have received reports of problems when users' kernels were older than their xf86-video-intel. It would be good if you report this at https://bugs.freedesktop.org/ if no bug report about this problem already exists, and provide the link here.
Were you able to test a newer kernel? Also try xf86-video-intel-2.21.15.
I just installed the last stable kernel (gentoo-sources-3.10.7) and xf86-video-intel-2.21.15 and now it's ok. I don't think that is related but, for futher information, I upgraded at the same time also cairo e pango. Thank you
