This issue started recently, and happens on and off, independent of the specific file. Any idea what's happening?
For some pdfs reflow is not a good choice.

So, cropping (if available ) is my best choice?
It depends on the PDF, there are a number of options in several menus, to try and provide a way to work around the differences in the various PDFs.

There are the "Zoom mode" settings (top menu) as well as Cropping (bottom menu). Landscape mode can be a better choice for some as well.
[I often use the "zoom to content width".]
