I had this problem, too. journalctl -b|grep glamor showed this:

/usr/lib/gdm3/gdm-x-session[2205]: (EE) modeset(0): glamor initialization failed

which is why gnome-shell was falling back to llvmpipe. However, there was some funny business going on with my libGL installation, because ldd /usr/bin/glxinfo showed:

 libGL.so.1 => /usr/local/lib/libGL.so.1 (0x00007fe67e633000)
 libGLX.so.0 => /usr/local/lib/libGLX.so.0 (0x00007fe67dccd000)
 libGLdispatch.so.0 => /usr/local/lib/libGLdispatch.so.0 (0x00007fe67da16000)

meaning I must have manually built and installed versions of libGL/X at some point. I deleted the libGL/X libraries and the xorg folder from /usr/local/lib and after a reboot I now have intel mesa graphics again.
