[Feature]: stop renderring pages when user slide very quickly #18315

Closed HairlessVillager closed 1 week ago

Is the feature relevant to the Firefox PDF Viewer?

No

Feature description

When I slide the pdf very quickly, the disk load will be very high and lots of pages will be rendered out of screen. I hope that when I slide the pdf at a very high speed, not all the page will be rendered.

Note that we already abort parsing/rendering of pages that are scrolled out of view.

Most likely this is a duplicate of e.g. https://bugzilla.mozilla.org/show_bug.cgi?id=1866296, however given the lack of a test-case it's impossible to tell for sure.
