Blurred documents after clip to DT

If I clip a webpage to DTPO via the sharing menu, as a one-page PDF, it is quite blurred in three-pane view.

If I open it in a PDF viewer, it is sharp.

If I preview (spacebar), it is sharp.

If I Print->Save as PDF… the same webpage, it is quite sharp in three-pane view.

If I clip, but save it as a paginated PDF, it is quite sharp.

I don’t remember this behavior of a one-page PDF in the past, although I could be mistaken.

Is there a setting for this?
