We don't do pdf rendering, poppler library does, so in any case this is a poppler bug. Someone recently posted https://bugs.freedesktop.org/show_bug.cgi?id=64855 which appears to be similar, feel free to create a new bug in poppler about this. |
If I compile LaTeX formulas in a pdf such as \begin{equation} \operatorname{util} = \overbrace{\alpha A + \beta B}^{\mbox{gains}} \overbrace{- \gamma C - \delta D}^{\mbox{costs}} \overbrace{- \epsilon E - \eta F}^{\mbox{penalties}} \end{equation} \begin{equation} d = \sqrt{\frac{123}{abc}} \cdot l \end{equation} there are imperfections visible or invisible, depending on the level of zoom. If I open the same file with Adobe Reader this does not happen. In the image I attached, you can see at the attachment of the "pieces" of the horizontal curly brackets there are imperfections, and the same holds for the square root symbol. I know this is a minor problem, but just to let you aware of it... Reproducible: Always Steps to Reproduce: 1. compile the pdf file with pdflatex 2. open it 3. zoom in and out to see the imperfections appear and disappear Actual Results: imperfections due to zooming interpolation (I guess) appear Expected Results: Perfect symbols
