I guess one such issue was a regression in mesa 9.0 found on 12.10
causing problems with KDE on some (older) intel hw. We need to offer the
latest releases in order to support newer hw for OEM's, it's not just
version chasing. We also have a MRE for mesa so we can push
point-releases as SRU which provides a way to fix such regressions and
other bugs of course.
The current packaging _does_ have something for Unity; reverts a couple
of commits which caused the blur effect to be painfully slow on a few
generations of Intel hw, easily noticed when alt-tabbing or opening the
dash etc. Upstream says this should be fixed on git master (which will
be released as 9.2 or 10.0 in August), but this hasn't been confirmed yet.
