Scrolling lag on annotated pages
Solus 4, Evince 3.33.0 Flatpak nightly, Xorg
When scrolling, there are some visible lags (up to 1-2 seconds) on heavily annotated pages just before the visible area enters the annotated page.
It'd seem at a first glance that those annotations are "lazy loaded" and rendered just synchronously (in the UI thread) as the page enters the visible area, instead of being rendered alongside the rest of the document at load time, which would slightly increase the loading time (or not at all if asynchronous, if possible) but avoid those stutters on each annotated page each time a document is loaded.
