There are several similar topics on this subject, but one was on Mac, possibly 2D only and another dealt with a really large model, but mine’s not that big and still:
And of course, the moment I stopped recording, the objects immediately began disappearing again when I switched back…
the camera frustum ‘view point’ might be getting ahead of the objects.
idk, I’m not able to recreate it rn though.
I’ve seen similar stuff happen, you pretty much have to record the screen with an actual camera 
I get this every now and then. Pretty annoying, also happens using a 3d mouse. Haven’t found a fix.
Assuming you are working in perspective mode but not sure… Perhaps this helps: go to parallel project and you will never have this issue. When you zoom in with perspective you are pushing the camera through the object so of course it can’t see it anymore. Parallel does not do that. Parallel is a camera infinitely far away that can zoom in infinitely with no perspective distortion and never gets ‘behind’ or ‘inside’ the objects.
