Last time I updated Unbutu something interesting happened the title bars disappeared.So I opened Synfig to see if it happened there also . Yes it did and found out you could still move and resize the windows.
Found out how to fix it. In compiz config settings manager goto window decoration click on the icon opens the settings. In Decorations windows replace word "none" with "any". So i next found out how to recreate the effect for a specific program.
Did some Googleing and found this.
In Decorations windows replace the word "any" with " !(name=synfig)" To remove title bars.
