Hey, i'm sorry but cannot reproduce your problem.. i have a machine with pop os 18.04 on a x86_64 arch machine and works fine. Could you try downloading again? or try with a previous release: https://mega.nz/#!OjBDkAZJ!ob1xbEqsbi5s8k3RP_BYeikSnKYCwCm0wPL0pwfOrf4
Have you tried in other pc? I've tried in Debian, Ubuntu, Fedora and Pop Os and could not reproduce your issue.. sorry.
