Comment 0 for bug 1164093

The Ubuntu X team would like to push mesa 9.1.1 for raring. It has been on a staging ppa for roughly two months now, and we've tested it on a variety of hw. During this time we've identified a regression with the Intel driver having a slow blur effect, causing issues with kwin and Unity dash. This was why we didn't upload it to raring before it got fixed upstream.

For me personally, it also fixes a bug in the Intel driver where compiz hangs after returning from another user session.

Upstream release notes for 9.1 and 9.1.1:
