(II) Loading /usr/lib64/xorg/modules/libglamoregl.so (II) Module glamoregl: vendor="X.Org Foundation" compiled for 1.17.0, module version = 0.6.0
You're using the old standalone glamor. Please try current glamor from the xserver tree (if you build xserver yourself, make sure --enable-glamor is passed to its configure script).
thanks a lot: everything is working nicely again (10.6.0+glamor) apologies for the noise
