Zoom page we 19.1 loads pages in 1 take, it takes a few seconds and the text becomes visible, no problem.
Zoom page we 19.2 loads pages in 2 takes, first with 'minimum font size on 0' then right after that the text
becomes visible with the right font size which in my case is 20.

The amount of time is the same in all cases.


It disturbes reading because the text first becomes very small and then normal size.
