Comment 16 for bug 376233

I'd also like to confirm that I'm having this problem. In any case, I found that if you export to LaTeX and remove the "\usepackage[T1]{fontenc}" line and then regenerate the pdf, the problem goes away. I can zoom upto 6400% without any blurriness or pixelation. This is rather inelegant but clearly theres a bug in that particular package that needs to be fixed.
