Bug Description

The essential X-Properties are missing or incorrect, making window-matching (Compiz, etc.) impossible.

$ xprop _NET_WM_WINDOW_TYPE | cut -d_ -f10
NORMAL

That should be: Notification

$ xprop WM_CLASS | cut -d\" -f2
<unknown>

$ xprop WM_CLASS | cut -d\" -f4
<unknown>

Those should report something at least, too.

Strange, both themes included with notification-daemon properly set the hint code-wise: the "bubble" theme sets the hint by subclassing GtkWindow and sets the property at construction-time, the "standard" theme creates it directly with gtk_window_set_type_hint() when it's making the window. On X, this /should/ set _NET_WM_WINDOW_TYPE, so this might be a bug in GTK+, perhaps pertaining to the recent client-side-windows merge.

Class-hints should also be set automatically by GTK+, which is why we don't call set_role() or set_wmclass() (beyond that it's broken, deprecated and non-portable).

Then again, I have to ask, are you sure you mean notification-daemon, or did you intend to file this bug against notify-osd?

No idea, honestly - I just noticed that window-matching didn't work
anymore and started to poke around with xprops.

In Jaunty, those classes are at least set "notification-daemon", though
the type is "normal", too.

Yes, notification-daemon indeed.

Then there's almost no way it could be notification-daemon's fault, the code has changed /very/ little since Jaunty (the theme code should be 100% the same, in fact).

Probably want to look into filing this against Gtk+ over at bugzilla.gnome.org.

You are right: Just cross-checked against Fedora Rawhide - it's the same there, too.
