I do not really know how to describe this, but it’s an issue with the studio camera focusing on something that it shouldn’t be.
This happens all the time (on my studio), steps to reproduce:
- Click the “Part” button (Home → Part)
- Using the “Select” tool move the part to the ground.
- Look anywhere, then scroll up (It doesn’t work with downscroll)
This can also be replicated by selecting a part and pressing “F”.
I have a GTX 1050Ti, I’m not sure when this started happening but I just noticed it today.
