When I hover over a window title bar, the selected theme (Breeze) is not respected anymore for the mouse cursor and it becomes a different cursor. This video demonstrates it (with a big cursor so that it's more obvious): http://stormi.lautre.net/fichiers/mageia/vids/curseur-2016-09-12_13.10.37.mkv
I also have the "different" cursor in eclipse that I downloaded from the official site. The KDE cursor them is not applied here. If we can't make sure the KDE theme is applied everywhere, maybe we should switch the cursor theme to one that will be appear the same everywhere (adwaita?).
I don't think this bug is valid any more. i don't see any particular behaviour of the mouse cursor in eclipse. I think this bug can be closed
