[Q&A]: Blinking when switching pages

[nayounsang]

hello. I am developing using React 18.
My project shows one pdf page on the screen.

<Document/>
  <Page pageIndex={pageIndex}/>
<Document/>

Users switch pageIndex to call setPageIndex() in [pageIndex, setPageIndex] = useState<number>(0);.
In the process of changing the page, elements are rebuilt and users see a white screen while doing so.
This is visually unpleasant.
How can I solve this? What methods are there?
I tried adjusting the zIndex of the previous page higher while loading to create a smooth transition, but that didn't work.
