Known Problems
Wireless is not available immediately after completing the Ubuntu System Configuration steps. Happens on every laptop once. Workaround is to reboot. Tracked by Ubuntu as #1573474.
Sugar startup graphics corruption
The first graphics drawn by Sugar after a reboot may be incomplete. Happens one every five times. Workaround is to open and close the frame (F6). Does not occur on Ubuntu 16.10 Yakkety, but does occur on Ubuntu 16.04 Xenial with Gtk+ 3.20.6. Should be fixed in the next release of Ubuntu.
Sugar Write activity flicker
The top of the Write activity begins to flicker once text is typed. Believed to be caused by Gtk+ 3.18 combined with Abiword 3.0.1. Does not occur on Ubuntu 16.10 Yakkety with Gtk+ 3.20.6. Should be fixed in the next release of Ubuntu. Not unique to Sugar, also occurs with Abiword. Several tracking tickets;
