Broken display roughly once every 10 to 20 times screenfetch is ran

[arbolis]

I have noticed that sometimes (roughly once every 10 to 20 times I'd guess, but I haven't made the real statistics), the display of screenfetch is "broken", i.e. misaligned, doubled lines and lacking lines altogether. I have noticed this on my university pc running Ubuntu and home pc running Arch. Here are 2 pictures showing the broken and normal state of my home pc: https://imgur.com/a/L24OO
