Description

I think I've traced it down to the intel driver, as it works correctly with Option "Shadow" "True" or if you use the vesa driver, so I'm reporting it here.

Bug description:

The use of true transparency on terminals that support it (e.g. urxvt, XFCE's Terminal, and gnome-terminal) causes certain window managers (e.g. Xmonad and awesome) to not display a border around the terminals as they should. When you use the VESA driver, everything works, albeit slowly, so I'm 99% sure it's the intel driver's issue.

System environment:
-- chipset: i915
-- system architecture: 64-bit
-- xf86-video-intel: 2.15.0
-- xserver: xorg 1.10.2
-- mesa: 7.10.3
-- libdrm: 2.4.25
-- kernel: 2.6.39
-- Linux distribution: Arch
-- Machine or mobo model: HP Compaq 8100 Elite Small Form Factor Business PC
-- Display connector: VGA

Reproducing steps:

Install xmonad, xmonad-contrib, dmenu, xterm, and rxvt-unicode.
Bring up X with Xmonad as your window manager.
Add the following to ~/.Xresources:
URxvt.depth: 32
URxvt.foreground:White
URxvt.background:[50]Black
run xrdb -merge ~/.Xresources
Run (alt-p, assuming dmenu is installed) xterm; note the border and how it activates on mouse-over.
Run urxvt -depth 24; note the same border.
Run urxvt (with -depth 32 if you really want to confirm the default); note the lack of such border.
