--- Comment #3 from Roderick Colenbrander thunderbird2k@gmail.com 2010-04-13 03:22:12 --- We do support transparency in some cases when XRender is around when you use 32-bit DIBSections and using a concept patch I submitted yesterday we also allow it for 32-bit DDBs.
I think the main issue is that systray bar we draw uses a 24-bit X visual (so it has no alpha). If it were 32-bit and an icon with transparency was drawn into it (this would depend on the app!) it might work. Right now we use win32 calls to create the window and I don't think we want 32-bit windows, so if this is the issue I'm not sure if we can fix it at all.
