Well, openSUSE 14.4 lies very far in the future when you take into account heat 11.4 is the highest supported level ATM and that 12.1 is in the one they are working on now.
As long as you even do not tell which desktop you use, it is a bit difficult for others to make comments on what you experience
EDIT: I now see this is your first post here. Be welcome. But as we are normal creatures like you we can not guess to much frome what you have/see/do over there. Thus shed off all nervousness and tell what openSUSE you have, what Desktop Environment (KDE, Gnome, other) and what you switched on/off on those desktop effects. This will make others able to get an idea of your setup.
