Saw it a few days ago here in the forums, and just saw it happen today during match
Ingame the Orb looked like stopping its course when reaching damaging distance from me, as a normal orb would; excpet it didn’t really slowed down. It just stopped moving; completely frozen from my point of view
And later on when I saw the replay, nothing strange happend. The orb never did anything weird in its path
A bugged visual effect only during game
I’ve seen that too, I thought that was a thing from the Junkenstein mode but then it started happening in a normal match too
Pretty weird looking
Might be a leak code from the event
can confirm i am facing the same issue
can confirm this indeed is very frequent than I though, In recent experience as a genji trying to deflect the orb (that too in comp 
) and not being able to determine if the orb is properly deflected is a major disappointment, and off course we lost the match due to this cause it seems this offers an unfair advantage to any team that has moira.
