I recompiled Fedora 21 versions:

libdrm-2.4.60-1.fc22.i686
xorg-x11-server-common-1.16.3-2.fc22.i686
xorg-x11-server-Xorg-1.16.3-2.fc22.i686
xorg-x11-drv-modesetting-0.9.0-2.fc22.i686
xorg-x11-drv-nouveau-1.0.11-1.fc22.i686
mesa-dri-drivers-10.4.7-1.20150323.fc22.i686
mesa-filesystem-10.4.7-1.20150323.fc22.i686
mesa-libEGL-10.4.7-1.20150323.fc22.i686
mesa-libgbm-10.4.7-1.20150323.fc22.i686
mesa-libGL-10.4.7-1.20150323.fc22.i686
mesa-libglapi-10.4.7-1.20150323.fc22.i686
mesa-libGLES-10.4.7-1.20150323.fc22.i686

and tried once more,
but the result is the same - "analytical cubism" - with Xfwm4 GLX build
$ xfconf-query -c xfwm4 -p /general/use_compositing
true


Interestingly, in contrast to Xorg-1.17.1,
on Xorg-1.16.3 NV30 can work with 'modesetting':
