[LO Impress] Loading previous slide takes a second while loading next slide is fast

As stated in the title, loading previous slide takes a bit while loading next slide is fast. I suppose next slide is cached to improve performance, but previous slide isn’t. Is there any option to also cache the previous slide? This is often useful if you switch back and forth to compare two slides.

Thanks for any hints,

Which OS are you using and which version of LibO?
How are you going to next and previous slide?

I’m using Arch Linux and switch slides with the arrow keys.
