I have a problem with my LyX PDF outputs.
When I export LyX file to PDF using pdflatex letters are thicker on a page where .png graph is inserted than on other pages. Same thing with 'LuaTeX' and 'XeTeX'.
Different problems occur when I use dvipdfm and ps2pdf. Then my graphs imported from .pdf files are blurred (low resolution) but there is no problem with thicker letters ...
