After the initial highlight of the actual item, I always have had a blue beam shooting out of the item that I perceived. I verified it stays a while after the first check because most other crpgs are awful at this too and just do a quick flash and you’re stuck wondering where the thing is. Haven’t had any issues in bg3
It doesn’t actually last that long. Multiple times, I’ve seen the check passed, swiveled the camera around like mad whilst holding down Alt, and not been able to figure out what the check was for.
Weird. I stared at mine for like 2 minutes, then went to the bathroom and came back and it was still highlighted.
