KDEV 5.0.1 line spacing question

[Leon Pollak]

Hello, all.
I am not sure that this is kdevelop problem, but still...:-)
The line spacing I had in 4.7.3 was about 15% less than in 5.0.1.
For example, opening a C-file in old kdevelop showed 52 lines of text, while 
in the new one - 48.5 (this half line is something strange, no?).
The situation in the "Project" pane is worse: 50 lines against 39.

Are there some options/parameters regulating this or is this hardwired?

Thanks ahead.
