ProjectWorldToScreen is incorrect in sequence rendering with AA multi spatial

Hello,

I am using the function ProjectWorldToScreen to show some widget on screen during sequence rendering. I noticed a weird bug, wich is happening during sequence rendering, that wasted me hours, maybe it’s a bug, or I am missing some info.

If I use AntiaAliasing 1_spatial/1_temporal, or +1_temporal it works as expected.
If I use Antialiasing 1+_spatial then the position of WorldToScreen is broken.

Please see the attached screenshots:

This is the BP function used to position the widget, by actor location:

Any hint is welcome, thankyou!
