Something a lot like this happens every time I open something up in Q-GIS, regardless of the file type, location, or even the projection: they are all too wide.
Note: I am using the WGS-84 "reference" system, which the program has carried by default, but have tried over a fifty-dozen different, other projections: some centered, some regional, some worldwide. But none of them happen to display properly on top of the application.
What may be causing this? I would like to be proportional, like-say Google Maps, any generic atlas, the available visualization tools, or ArcGIS would have it.
EDIT: a few people have referred me to the following link. However, besides the fact that it doesn't even address the question as intended, only the WGS and a few variations thereof even show up on the map-files that I have created: as soon as I switch the layer/overall CRS over to literally anything else, the whole editor's usage-made screen goes blank, and only re-appears to pop out once I flip it back. Maybe, something-that is (unrelated) though, I don't know?
To clarify, and respond to @user's questions:
