Created attachment 102046 [details] screenshot The left aprt of arrow ending is not equal to the rightest
How did you generated these dotted line ? At the top I see a class conntected to a dependency, but the second widget is unclear.
I went to right click on the line -> Properties -> Style -> Line width -> changed line width from 0 to 1 and pressed OK
Second widget is class too. The line I've created is "Dependency"
Arrow line style has been changed to solid.
