Hi @Kerogaz,
I believe it is a part of Libreoffice, as I’ve had no issues with mine, yet haven’t installed one explicitly.
I am completely unsure of why it’s doing that if you’re using Libreoffice, but if it does then you need to provide more information for anyone trying to help. To that end, see How to provide good information and, if applicable, see [HowTo] post screenshots and links.
Hope you figure it out!
