Description:
Starting with LO 7.1, on OSX 11.2.1 Impress doesn't scale correctly the slides on a second screen. 
The slide is correctly displayed on the large screen (here 1920x1200) (see pict 1).
But looks much smaller when the window is moved to the second screen (here 1440×900): see pict 2.
When I try to zoom in, the content scales, but the slides size doesn't change, so the outer content is hidden, and is badly treated when moved around (Pict 3).

 

Steps to Reproduce:
1.Open on two screen OSX
2.Move window to the smaller screen
3.Zoom in

Actual Results:
Slide doesn't zoom; only the content does, and it is truncated.

Expected Results:
Slide scales with the zoom until it reaches the board of the window.


Reproducible: Always
