Display not properly refreshed
In the latest versions the screen often isn't refreshed properly. Only after rescaling or changing to Preview mode the old data is hidden.
Thank you for reporting the issue to us.
Can you share a test document to us on firstname.lastname@example.org?
It will help us investigate into the issue.

Not sure if I am seeing exactly the same thing, but I do see refresh issues.
For example, in an existing document select a paragraph and change its style to one that needs a few pixels more height. In some cases, this works properly but in others the newly moved following content overwrites the pre-existing display, making a right mess, until the app has cause to re-render it (e.g. with zoom, pageup+pagedown, etc.)
I regret I cannot see a pattern for when this bug hits, nor provide a definitive reproduction steps, but it's definitely there.

This has been the case for me as well. When I page through a document, the pages display as blank, until I click in a text frame. So if I go through a document spread by spread, I have to click in each text frame, on each page, to see the contents.
I've found quite dramatic examples of this happening. I can make changes to text and images in Normal View, then I switch to Preview and it is displaying the older layout/text of the page.
Sometimes this happens instantaneously but more more worryingly I have scrolled through a document and seen elements revert back to how they looked days again before several rounds of amends, except they aren't really there, they're just like ghost elements that when clicked on eventually refresh to what they should be. I don't even understand how the files are retaining such old previews of the pages.
