Hello,
it appears xcompmgr does not decorate windows with ARGB 32-bit
visuals; which at first sight seems probably a preference of
artistic taste than a result of engineering considerations. :-)
By the attached tweak may I suggest to turn this fixed setting into
an optional choice by command line boolean parameter '-A'. I.e. in
this case the computed shadow picture is cleaned in the middle
partially, in particular pixel-exactly covering the area of the
spoken window including its border, by XRenderFillRectangle() in
win_extents() in xcompmgr.c.
The attached patch should apply cleanly ontop of the 'Proposal:...'
as posted on
http://lists.freedesktop.org/archives/xorg/2009-September/047302.html
otherwise the hunk
