Same bug exists with "Project Mind" when playing as Wraith - the indicator for where she will appear doesn't appear the first time the ability is cast in a match.
Attempting to cast it, cancelling it, and then starting the cast again doesn't resolve it either, it must be successfully cast to fix this issue.
I was able to reproduce the issue with McGinnis using her turret and healing ability. Playing on a 144hz monitor averaging 220 FPS in case client tick rate has anything to do with it.
