TL:DR: Is there a solution to fake overlay with mutiple frames?

As explained here I would like to add multiple backgrounds to a same set of overlays. This thread gives a few solutions, but none of them is perfect: the first solution adds some margin, so one need to arbitrary increase the background until no margin is visible which may zoom a bit the background image, and the second solution seems better, but it adds new pages. Basically, this second solution adds some frames by adding new pages via:


but unfortunately this adds new pages instead of overlays:

I managed to solve the page numbering problem by using some \addtocounter{framenumber}{-1}, but unfortunately the miniframes (the dots in the top left part) are still bad...

Is there a solution to fake overlay with mutiple frames?



\setbeamercolor{separation line}{use=structure,bg=darkred!80!black}

  Hello, I'm a new empty frame

-- EDIT --

I finally found a problem to my original problem here, so I don't need anymore to solve that one, but of course I'm still curious to ear about answers.

  • Maybe tex.stackexchange.com/questions/234269/… could help?

  • @Marijn it's a first start indeed thanks: it removes the dots, but does not highlight the dot of the current frame. Note also that I found a solution to my initial (different) problem (see edit), so I don't absolutely need the solution, but I'm quite curious to know if there is a solution.
