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.
Daniel
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... :-)

Yes LyX creates a PNG file for the on-screen preview within LyX (It also does
this for the math preview)
If you dig into the LyX temp directory you will find all of the PNG files.
I recall that an older version of LyX (on Mac) did not use PNG for on-screen
previews, in which case it may be possible to revert to the older behavior even
in 2.3.X?
There are fundamental differences between the handling of SVG and PDF files in
LyX.
LyX is using Qt plugins to render the images on screen.
For PDF files one has to convert them to temporary bitmap files because there
is no plugin to render them directly. (Perhaps this is not true anymore.) For
SVG files there is a plugin. But this one is limited in functionality. There
was a decision to not use it for on-screen display because of the complaints
regarding missing details.
The problem with the temporary images is the fixed resolution of the generated
images. The used cache is not invalidated in case of higher preview zoom
levels. Furthermore you can have different resolutions at runtime too. In case
of a machine with multiple monitors with different physical resolutions you get
different values for moving the LyX window around.

This makes sense. Do you think it is reasonable that I put this as a
wish to the tracker?
I think it’s already there… but couldn’t find it ATM.

I opened a ticket as a request...
