GNOME Shell 3.9.4 finally adds support for “box-shadow: none” and optimizes box-shadow rendering. However, support for fixed positioning in BoxLayouts has been removed, and focus handling has been rewritten. GNOME Shell 3.9.4 fixes autorun notifications for “non-native” volumes, chat entries not being focused when expanded, the alignment of the “Not Listed?” label, the alignment of time stamps in chat notifications, and management of asynchronous background loading. Moreover, GNOME Shell 3.9.4 keeps chrome below pop-up windows, rounds the ends of slider trough, moves the session list to a pop-up menu, and makes the draggable much faster.
