Bomb them again! bugged?

Hello, I've been trying to complete the "Bomb them again!" quest for the achievement, but when I get close to the cannons they shoot me (as intended) but I can't see the fireballs coming so even if I try my best to guess their route I eventually get hit, I don't know if it is a bug preventing me from seeing them or just my machine being old as it is, if someone could confirm this for me please I would appreciate it so I could make a bug tracker report

Also for the sounds effects I think each cannon is shooting like 3 fireballs each time and that's not how it's supposed to be

Thank you
