this is missing some updates to
        memset(ptr, 0, avctx->width * 6);
        ...
                // Zero out the start if xmin is not 0
                memset(ptr_x, 0, xmin * 6);
                ptr_x += xmin * 3;
...
                memset(ptr_x, 0, (avctx->width - (xmax + 1)) * 6);
                ptr_x += (avctx->width - (xmax + 1)) * 3;
...
        memset(ptr, 0, avctx->width * 6);

If a bugfix only changes things apparently unrelated to the bug with no
further explanation, that is a good sign that the bugfix is wrong.
