So you can basically assume to almost never find a "real" kde5 / kf5 bug, but a
bug in the underlying qt5 plugin. Most of the code in kf5 is just boilerplate.

/me also tried sloccount, but that doesn't seem to account header files...

So I very much assume you're right and this is a dup of bug 125201, so I'm
closing is as that.

Smooth scrolling isn't yet implemented, nevertheless current scrolling
implementation in 6.3 should fix the erratic behavior you reported in this bug.

*** This bug has been marked as a duplicate of bug 125201 ***
