this is not a bug or a problem.
It is just a way to make faster indesign when you scroll the pages
it is a sort a dynamic display performance (these options doesn't affect the print quality or exported output).
Thank you. But is there any way to shut this off? My computer already fast enough I don't need that.

No. I think the best you can do is click the window scrollbar's up and down buttons instead of dragging
Unless you're making colour judgements while scrolling, why does it matter?
