save screen on a frolic of its own!

All of a sudden, the background colour of LO Writer’s save screen has tuned black and the text blue. Impossible to read really. How did this happen? and how can I return the screen to its original white/blue setting?

LO does not contain a screen saver. Your OS does. This may be an unwanted interaction between OS and LO.

Edit your question (don’t answer) to provide OS and LO versions.
