This is a known problem -- it is an outcome of the node connection drawing algorithm. Feel free to complain to Xerox support -- it could help in prioritizing the issue.
I have several cases where adding just 1 new node or connection introduces enormous spaces between nodes, with connectors stretching more than the entire screen length for no reason, nodes go completely offscreen.
Even simple workflows become unreadable.
Like a sequence of 5 nodes taking almost the entire 1440p screen in length, its ridiculous.
What's happening? How do I prevent this?
It is also not a glitch with a particular workflow - if I completely recreate it from zero, I end up with the same results every time.
