adding label stretches horizontal arrow between use cases

Question

Hello,
I have the latest plantuml.jar (Version 1.2020.1) installed, and for some reason, I get stretched arrows for use cases when running plantuml locally. e.g.,

However, running the same plantuml syntax through the plantuml servers seems to work just fine. e.g.,

It may be related to your graphviz version. Could you check it ?

When using dot version 2.38 (dot - graphviz version 2.38.0 (20140413.2041))  I get the short line graph (the bottom image), with version 2.40 (dot - graphviz version 2.40.1 (20161225.0304)) I get the long line one (top image)

Good news: with graphviz version 2.42.2 installed (report 2.43.0!!!!), it is like 2.38

Good to know that there is a newer graphviz version, did you compile from source or where did you find the executables?

My colleage do a test on his own linux at home with last Fedora. For our old linux, he compile it from sources.

For Fedora for example: https://apps.fedoraproject.org/packages/graphviz
