Not possible to have shadow on gnome-terminal windows with no decoration

[Jeremy Kerr]

Binary package hint: compiz

I have the following settings in CCSM:

Window Decorations -> General -> Decoration windows: "(any) & !(class=Gnome-terminal)"
Window Decorations -> General -> Shadow windows: "any"

(corresponding gconf settings listed below)

Gnome-terminal windows correctly have no window decorations. However, they also do not have any shadow.

It looks like the shadow is only ever applied to decorated windows; this makes it impossible to specify "shadow, but no decoration" on windows.

gconf dump of /apps/compiz/plugins/decoration:

 /apps/compiz/plugins/decoration/allscreens:
  /apps/compiz/plugins/decoration/allscreens/options:
   shadow_color = #000000ff
   command = /usr/bin/compiz-decorator
   mipmap = false
   shadow_opacity = 0.5
   shadow_x_offset = 1
   shadow_y_offset = 1
   decoration_match = (any) & !(class=Gnome-terminal)
   shadow_radius = 9
   shadow_match = any

I use the Titlelesser gnome metacity theme from http://gnome-look.org/content/show.php/Titlelesser?content=82972 which enables the shadows.

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. Compiz, in particular, is in heavy development and this bug may have been fixed in the development version of Ubuntu (12.04) if not on your current version. If you are able, it would be of great help if you could confirm if the bug still exists by testing a livecd (available at ubuntu.com). When you test it and it is still an issue, kindly upload the updated logs by running apport-collect <bug #> and any other logs that are relevant for this particular issue. If you are unable to test the development version, please let us know if you are able to reproduce this issue on Ubuntu 11.10.

Thank you for your help and patience.

Can still reproduce on the 12.04 alpha.

However, after some further digging, this looks specific to gnome-terminal windows; as described above, I have the following settings:

 Decoration Windows: !(class=Gnome-terminal)
 Shadow Windows: all

- in order to remove the decoration (but not shadow) from gnome-terminal windows. With these settings, gnome-terminal windows have no decoration *and* no shadow, which is incorrect.

However - if I set the 'Decoration Windows' filter to that of another app (eg, 'class=Ccsm'), then that application's windows are correctly rendered (no decoration, but with shadow).

So it appears to be specific to some apps only?
