[Inkscape-user] Question on text colors of info boxes ...

Dear listmembers, I am quite happy with Inkscape (V 0.91 on openSUSE 42.1 with kde) with one single exception I could not find a solution for until now:

Whenever I move the mouse - curser over an icon say on the left upright bar with different symbols (for example the selection icon) a help text is displayed.

Unfortunately this text is white on a light gray background: long text short answer: one can hardly read what is shown in the box.

Could any kind soul shed light on this and (maybe ...) tell me how to fix this problem? Any pointer is greatly appreciated, many thanks in advance, take care
