Description:
Hello,
I read the interesting article about the new Vulcan graphic library in the
current LibreOffice.
https://www.collaboraoffice.com/releases-en/implementing-vulkan-capable-libreoffice-user-interface-using-the-skia-library/

This apparently makes everything a bit easier to implement and there is also
talk of possible improvements.
I would like to make a suggestion for improvement, which is perhaps not so much
dependent on the engine, but on how the implementation of LO is realised.

Every year we publish a lot of books where usually two illustrations/photos are
linked on a double page. This still all takes place in MS Word 2003 in Windows
(but I would like to swich to LO). Unfortunately, I have to say that scrolling
through the double pages in Word is a lot smoother than in the current LO.
I think this is due to a different type of "lazy loading". Word turns the page
and I, as the producer, see the double-page text immediately on the screen.The
illustrations are sometimes immediately in place, or loaded with a small delay. 
LibreOffice, on the other hand, seems to wait until the photos are completely
loaded before the double-page spread is displayed on the screen. This is
irritating for my use case. I would like to see the texts turn immediately, the
display of the illustrations is secondary for me.
I would suggest to change the behaviour in principle or to offer a switch in
the basic settings to be able to activate the "lazy loading" when scrolling.

Thank you 
Michael Mueller
