commit 9da241b2d0251cafa30a9da13d0299e496a9bded
Author: Olivier Fourdan <fourdan xfce org>
Date: Wed Mar 11 13:52:21 2015 +0100
Improve CSD decorations without a compositor
It turned out that using mwm hints to instruct wms to
create border-only decorations is not really working
universally. So, instead of doing this, render a solid
frame without shadow on the client-side to handle this
case.
