Kwin is buggy in that it does not always set focus to the window under the
mouse pointer, no matter what settings you use in order to make it do so.
 That seems to go for all windows, not for only a particular application
like gvenview.  It's pretty annoying.

Are you sure that gvenview does have the focus when you try to close it?
 You need to move the mouse pointer between some windows to make kwin catch
up with it, and that's not something you would be likely to do while
gvenview is in fullscreen ...
