In case you missed it, this site is support for LibreOffice.
Have you checked over at https://forum.openoffice.org/en/forum/, or are you, in fact, using LibreOffice?
I am using libreoffice. However, the problem also occurs using Openoffice! Since both use similar core code, there is something in that similar code which has this bug.
A similar issue with Impress Remote: tdf#120326.
I believe that you need to look at SlideShowImpl::setProperty; namely, its
PointerPosition should call a function that would notify OS about user interaction (and that code, as mentioned in the bug I mentioned above, must be system-specific, so likely would need to be implemented in VCL).
Please start with a bug report - you would need it anyway when you would submit a patch (unless you intend to create it privately, without sharing with the community, and intend to support a private patched build for unspecified time).
Thank you so much! It is now bug #149853 and I am learning how to develop with LibreOffice! Again, Thank You!
