Hi Umberto,
I have a Zoom 1.0 and no wideview activated.
But even then at a relatively short distance the jetways disappear. I only have this with jetways created with GSX, I don't have this problem with other airports.
To be precise, I have the problem at two airports out of around 200. However, it's all payware, I only revised one of them myself.
I attach a Screenshot that shows the distance and the missing jetways
