I can confirm this bug, it happens for me too. It looks like it could be an
issue with rendering the images, because it only lags when scrolling to parts
of the document that haven't yet been viewed. 

While scrolling, it seems that libreoffice is using up approx. 50% of the
processing power on a core, more than the usual amount. It isn't hitting max.
frequency at all, so I don't think putting too much work into one thread is the
issue.
