ArcGIS Pro 2.4.1 - Why ArcGIS Pro freeze display when pan & zoom out of projection extent?

I am having problems when trying projections for mapping in ArcGIS Pro. For a given project, it is always recommended to use the most suitable projection in order to reduce shape/area distortion... It is sensible.


However, in ArcGIS Pro, any time I try a projection on the geographic extent of my project and/or accidently pan & zoom, the display (and the application) freezes just as if ArcGIS Pro could not "calculate" and project the data. To minimize computing, I also take care to use an unique datum. Thus projection seems to be the issue!


For example, a data frame set to the built-in Europe Lambert Conformal Conic projection (in WGS84 and not the ED50), opening a WGS84 (non-prejected) country polygon dataset, it freezes the application... In ArcGIS Desktop 10.5.1, it takes 20 sec to display.


Why is this happening in ArcGIS Pro?
