Seems it's fixed in 8.5 now (see below)
I noticed Hans had changed submenu delays to infinite - if it was to avoid
compiz glitches it can be changed back now.

Summary: Compiz animates each menu item as a new window

Initial Comment:
Compiz somehow thinks that the menus of these apps are separate windows and
applies window open and close animation to them. Thus each submenu "pulses"
like ordinary window when opened and navigating a menu (specially one with
zero delay) looks like a firework.

Message:
Applied this patch to HEAD and to 8.5 branch.
A separate patch (possibly done as a TIP) will be done to make it possible
to handle the combobox dropdowns, tooltips and other window types from
script level.

Updated patch with feedback and code from patthoyts.
Menus show sensible behaviour in both normal and tornoff states now.
Patch against HEAD.

You are right (I was reading an old version of the document).
I tried setting _NET_WM_WINDOW_TYPE_MENU for torn-off menus and
_NET_WM_WINDOW_TYPE_DROPDOWN_MENU for normal menus. The result is the
same for normal (override-redirect) menus, but for torn-off menus the
result is a window which doesn't have an icon in the applications bar
but is not transient of the [winfo toplevel $menu] . This can resut in the
menu going bottom of the window stack without the user noticing.

I think we can do two things in this scenario:
* For torn-off menus, we set _NET_WM_WINDOW_TYPE_NORMAL and it behaves
like a normal (animated) window. This is the default now.
* For torn-off menus, we set _NET_WM_WINDOW_TYPE_MENU and
WM_TRANSIENT_FOR to make the menu transient of its toplevel, so it
doesn't get lost behind other windows.

I don't think Tk can distinguish between a "normal" menu and a "popup"
menu, so _NET_WM_WINDOW_TYPE_POPUP_MENU is out of discussion.

Note that these additional properties were not described in EWMH 1.3, but
instead form part of EWMH 1.4.

Message:
Actually, it wants to be one of:
1. _NET_WM_WINDOW_TYPE_MENU - for torn off menus
2. _NET_WM_WINDOW_TYPE_DROPDOWN_MENU - for "real" menus from the menubar
3. _NET_WM_WINDOW_TYPE_POPUP_MENU - for menus that are neither of the
other two (i.e. posted with tk_popup)

Message:
Apparently new window managers expects additional information to be set
about what the function of the window is.
More precisely, it expects the _NET_WM_WINDOW_TYPE property to be set to
_NET_WM_WINDOW_TYPE_MENU for menu windows. See
http://standards.freedesktop.org/wm-spec/1.3/ar01s05.html .
A patch against HEAD (5 dec 2009) adds this information to menu windows on
x11.
As a result, the new property is set for menu windows as shown by xprop
output:

_NET_WM_WINDOW_TYPE(ATOM) = _NET_WM_WINDOW_TYPE_MENU

For the patch, see http://paste.tclers.tk/1880

Message:
The menu code is very scattered over different files, but the key part
appears to be in tkUnixWm.c in the function to create the actual X window
for the menu (TkpMakeMenuWindow). If I'm reading that function right, the
override_redirect flag is not being set on the menu until after the window
is created, and maybe compiz is not noticing that. Can't tell, as I'm not a
user of the right platform...
