What I was trying to say is that I don't know whether changing
"Screen DPI" simply changes the math preview size and has no other
side effect, whereas \preview_scale_factor for sure works like that.
The right fix would be to know why the screen DPI is changed with
respect to 1.4. However, if you know what is the correct value for
screen DPI, then you could force the right appearance by using the
following lines in lyxrc.dist (replacing the numbers as appropriate):
\screen_dpi 90
\screen_zoom 150
\preview_scale_factor 0.9
In this way you can control both text and math preview sizes.
