Qt5.5: X11 video window broken, cropped

Since yesterday, both with official VideoLan and Packman packages, VLC is not able to show the video in fullscreen mode anymore. It only shows a quarter of the video (see attachment)

Furthermore, it does not respond to the "f" shortcut and I lose the mouse cursor when I move it insight the video area.

I have tried some other video output plugins (e.g., openGL) but it does not fix that behavior. Xine works well, but I do not know how many (video) dependencies it has in common with VLC.

How can I run a better diagnostic? What information do you need? I am running openSUSE Tumbleweed with all packages updated yesterday.
