[ubuntu] Unity3D top panel + left launcher COMPLETELY transparent

view story

http://ubuntuforums.org – Hello, I have problems setting top panel and launcher backgrounds ABSOLUTELLY transparent after two days googling and trying it seems that it is impossible. At first I tried using unity plugin in compizconfig manager. At low values like 0.01 it is still far away from transparent as you can see in first screenshot. Also tools like ubuntu tweak ao MyUnity did not help. Setting transparency to value zero makes panel completely transparent but causes another bug where previous "global app menu" stays at panel, see the second screenshot I saw some workaround to disable P (Hardware)
