Did you also get the following log information:

[ 71790.287] (II) fail to get matched format for 7893d260 
[ 71790.287] (II) fail to get matched format for 7893d260 

>From the back trace log, glamor fail to download a valid sub_pixmap for
the input 1x1 pixmap. Please see code in glamor_get_sub_pixmap().

...
    data = glamor_download_sub_pixmap_to_cpu(pixmap, x, y, w, h,
sub_pixmap->devKind,
                         data, pbo, access);
    if (pbo) {
                //we should check whether the data is NULL.
                // if the data is NULL, we should destroy the sub pixmap and
return a NULL pointer. And we should also back trace why we get a NULL pointer. 
        assert(sub_pixmap->devPrivate.ptr == NULL);
        sub_pixmap->devPrivate.ptr = data;
        sub_pixmap_priv->base.fbo->pbo_valid = 1;
    }
