Created attachment 116902 [details] screenshot of problematic dialog buton. Dialog box button with focus in LO 5.0.0.1 -- the text label for the button is obscured by the focus selector. In OpenSuse 13.2. See screenshot. No reboot attempted after install. This is the way it looks on first start. This is what happens in all dialog boxes.
Seems you are using a LO-version from OpenSUSE. I have tested with OpenSUSE 13.2 64bit rpm Linux and LO 5.0.0.1. Could not confirm the missing text-label.
