Flickering pages
When I switch colors in output preview, the screen flickers.
For example, here at time 1:08-1:20: https://youtu.be/ShbafbUx9FU?t=68
When output preview is enabled, the screen also blinks when browsing between pages.
This is a "feature" of Acrobat DC, older versions work correctly.

  Same here, very annoying and bad for the eyes, sometimes I wonder why doing this sometimes for hours has not caused any epileptic fits yet ;-)
Turning Page cache on and off makes no difference, nor does turning off Overprint Preview or changing the Simulation profile.
Uploading two examples, just paging through a few pages of simple text, with and without the Output Preview window open. -

  Was there ever a fix for this. Just got a new computer and am having this issue.

  It appears to redraw the page 2-3 times and causes a flicker/flash when the Output Preview window is open when changing pages.

  I have the same issue and it makes comparing things from page to page very difficult?
