Created attachment 104162 [details] screenshot Hi, here is a screenshot that illustrates the problem. It shows that at the bottom of the gnome-terminal window, there is no decoration. The gnome-terminal window has been maximized vertically using a middle-click on the maximize button. Note that starting "gnome-terminal" alone is not sufficient. You have to start gnome-terminal with the "--hide-menubar" option. Here is more precise version information: Package: kwin-x11 Version: 4:5.9.2+p16.04+git20170221.0458-0
can you reproduce the issue with any other application except gnome-terminal?
No, only gnome-terminal --hide-menubar exposes this issue.
Small addition to my previous comment: the issue can also be reproduced with mate-terminal 1.16.0 (a version compiled with GTK3).

This bug does not exist in Kubuntu 17.04 with this package version: Package: kwin Version: 4:5.9.4-0ubuntu1 Were you able to reproduce it? If not I would like to close it.
Feel free to close it. I assume it changed in gnome-terminal then as I'm not aware of anything in KWin that matters between the two mentioned versions.
