Hi,

Most likely you're using a modified version of weston, and a rather old
one. Passing `--use-pixman` option to the DRM-backend is not conditioned
by additional macros which are sprinkle's by the vendor in that version
you're using. If you can get a hold of the upstream version of weston
you shouldn't have any problems using the pixman renderer. But also
even that older version should work. Probably you'll need to reach out to
the vendor for additional  help.
