I have discovered some strange behavior in the outermost lines that converge in 3-point perspective.
This pertains specifically to those lines that form the vertical convergence; i.e., the vanishing point that is way up high above the image.
So, when I grab the handle to move the left outermost line, the line itself disappears maybe 20% from the left edge of the image.
The handles are still there, but the line is gone.
Then, when I move this left line rightward, the line reappears! It's as if something is hiding it if it moves too far left. Strangely, the RIGHT outermost perspective line for this same VP stays visible at all angles.
It seems like a bug to me, but maybe there's a logical explanation.
I'm open to any guidance you may have.

Hello Steve, sorry I am not able to recreate this issue. I tried moving all of the lines with the various handles but I don't get any disappearing lines. If you can send a video, that would be helpful.
Hi! Thanks for getting back to me.
I was not able to upload my short MP4 file, so uploaded it to my Google drive. Here's a link:
Keep your eye on the left-most vertical perspective line. It will disappear as I drag the line to the left, and then re-appear as I drag it back to the right.
