Created attachment 131967 [details] Border size set to none SUMMARY I prefer to set window border size to none, which is default value for Breeze theme, and all applications follow this value except System Activity window. Moreover, if set window border size to normal, then the border size of System Activity window becomes huge. This came after the commit 42e2078cfd41396ceb6d78746f2ebbdd53b11ee8. I guess that margins should only be around the buttons, not the ListView.

There is no window border here, the border you are seeing is drawn by the application inside the window, not the window (decoration)
> margins should only be around the buttons, not the ListView Makes sense.

Actually there have previously been margins around the complete window in older Plasma/frameworks versions, but some refactoring incorrectly removed them, which regressed the missing margins around the buttons. See also bug 315400.
It's not ignoring the border size option; the window itself adds margins around the content items *in addition* to any borders provided by the window decoration theme. Being a dialog window, the margins that it adds are larger than the margins added by non-dialog windows. Before 42e2078cfd41396ceb6d78746f2ebbdd53b11ee8, the effect that you want was still not possible. Rather, the list view frame was still drawn, but it was touching the window edges, which looks bad. What (I think) you want is for the list view to have no visible frame and to touch the left, right, and bottom edges of the window. In order to do that, we need to make a lot of other UI changes, such as turning off the listview frame and all internal margins, and then add margins to the button row. Basically we have to stop assuming that there will always be some kind of margin around the window itself. This is a duplicate of the issue that Bug 315400 was attempting to report. I have re-opened it, as it seems that I closed it in error. *** This bug has been marked as a duplicate of bug 315400 ***

Yes, see the duped bug.
