There is no page preview when zooming in/out
When I zoom in using the ctrl+two-finger-scroll(on trackpad) or even ctrl+mouse-wheel or just ctrl+-/ctrl++ it doesn't give me a preview and I have no idea how much I'm zooming in or out. The whole document just goes blank (gray) for a couple of seconds and then it renders the page. It'd be nice if I had some low-res preview when zooming in/out.
