I can't reproduce this. In my case, the blur is active, and gets updated.

Probably this is driver related?

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Hernando Torque (htorque)]

Dupe of bug 901178?

Quicklists, item tooltips, dash - all affected here as well (x64, Intel HD Graphics 2000 and 3000).
