Comment 5 for bug 1514491

I hope it is okay that I add some issues here that I think are related - if not, please let me know and I'll create a separate bug.

There are some other L&F inconsistencies for me since upgrading from 15.10 to 16.04 Beta2:

- KDE4 applications like Amarok now use some other style
- Eclipse with GTK2 and Thunderbird now uses plus signs for tree node handles instead of rectangles
- Eclipse with GTK3 has a dotted line at the lower and right window edges

All of them looked consistent in 15.10 (besides Eclipse with GTK3 which looked kinda broken but looks much better now).

Please see attached screenshot incl. one of Dolphin which looks fine of course (tree nodes, scrollbar).
