Hello,
PDF graphics appears to be blurred in LyX when scaled from Graphics
Options --> LaTeX and LyX options --> Show in LyX --> Scale on Screen.
I am not sure if this is a feature to reduce CPU rendering workload or
smtg, but it would be really nice to have a clear view of the PDF
while working on the document rather than looking at it using a PDF
viewer.
See MWE and the view from LyX below.

The image in your PDF file is a bitmap (PNG), so I don't hold out much
hope for being able to zoom it without loss of fidelity.
Why do you think the graphic in the PDF is a bitmap? I have zoomed in on
it and never got any pixels to see. At least it must be an extremely
high resolution bitmap then.

Because PNG format is bitmap?
PNG image data, 652 x 668, 8-bit/color RGB, non-interlaced

The external graphics is in PDF, which is attached to the original
e-mail; it was generated in Tikz, so it is a vector graphics. No
question about it. When inserted into LyX, maybe LyX creates a
temporary bitmap or PNG file to show to the user, I am not sure.
It should not be a big thing to show a higher resolution graphics or to
let the user decide for possible performance issues. One day I will be
doing all these small modification by myself, but when that I do not
know... :-)
I think the converters for graphics should be in
Preferences > File Handling > Converters
And the converters for the particular task of PDF to bitmap conversion
seem to be
PDF (graphics) -> EPS
and
EPS -> PNG
However, I tried to make some changes but LyX did not respond to any of
them except for a complete removal of the converter. I believe you need
to at least restart LyX to see the changes but nothing worked for me
even if I filled in complete gibberish. (Also, be aware, it seems
removing a converter cannot be undone easily. You can reconfigure which
might overwrite some other changes you made in Preferences. And even if
you do so, LyX does not save the converters, so you have to go to the
converters make a change to one of them, like adding a letter, click on
modify, removing the letter, click again on modify and then Save ...
quite a pain.)
