tags is overlapped

[thanhbx]

tags is not generated perfectly on my server. they are overlapped and incorrect position and size

Here is my simple code

from pytagcloud import create_tag_image, make_tags, LAYOUT_HORIZONTAL, LAYOUTS, LAYOUT_MIX, LAYOUT_VERTICAL, LAYOUT_MOST_HORIZONTAL, LAYOUT_MOST_VERTICAL
from pytagcloud.lang.counter import get_tag_counts

text = "abc sda 123 343 hello world asia innovation djaksdja daksjdaslkd alkdha djhasjkdahskjdahsd kjasdjkasd jkah dakj djfsdhf kjsfhd sdjfhs kjfshd k"
tags = make_tags(get_tag_counts(text), maxsize=80, minsize=20)
create_tag_image(tags, '/home/hoanghua/cloud_large.png', size=(900, 900), fontname='Lobster')

Please help me to find out the issue. Thanks in advance
