background of group is non-transparent (TEOZ)

Question

Try the same flow, once with and once without "!pragma teoz on".

 

Note the difference in the background whre the letters "A1" are drawn.

 

I think the non-teoz is better.

 

 

!pragma teoz on

box "B"

participant "AAAAAAA" as A

end box

group

A->B: A1

end

 

Answer 1

Remarks also shadow that is under box with non teoz !

I also prefer non teoz but with group box over participant's box.

Answer 2
