My program's icon is missing (in the upper-left corner of a window).
 my transparent window not transparent.
Anybody knows answer to either of the above questions? I understand I need a compositing window manager and additional X server extensions to make  work but I don't know how to get/configure those (A document would be great).
First issue have been fixed in upcoming release.
For second issue please check if desktop effects are ON for you or not? please reply at firstname.lastname@example.org
Transparent windows work only when desktop effects are ON for a user.
