example 1: In the general tree there is this weird effect where 3 skills fit on the left part(x=0,1,2) and then the spellbooks on the right part(x=3+) however sometimes the spellbooks get pushed one space to the right producing a gap between 2 and 3:

example 2: In the path screen x=0 is the left border only in the first row, every row from then on starts with a gap to the border!

what causes these effects?
