YARAQ (Yet Another RGBA Transparency Question)
 

My head will explode... no, seriously what's wrong with the Cairo GTK window transparency in maemo? I'm doing everything by the book, but still no luck (just to mention that i don't want to make an application main window transparent, but a GTK_WINDOW_POPUP in it). Everything works, but the popup background is not transparent whatever i do.

Any hints? Pleeease? :D
