Decoration shadows shown, but not decorations (for evince)

[KristianLyng]

Evince seems to do it's own decoration, gtk-window-decorator seems to respect this mostly by not drawing decorations for it.

However, the shadows are still drawn as if g-w-d was drawing the decorations (and with a rather large border).

Things that strike me:

• Not a problem with chromium (which also draws it's own decoration)
• Resize is not confused: Resizing is triggered at the correct places, not at the shadow.
• There are technically two set of shadows: The correct shadows (displayed regardless of g-w-d), and the bugged ones.
• The extra shadows are way too far away from the window for this to just be the regular g-w-d shadows (I'd say it's 20+ pixels away, which makes sense for the top, but not the bottom and sides).
• It's just a shadow, it's possible to click through.
• Same problem with emerald OR g-w-d.
