Issue #142 resolved

# Block corners are distorted when using pdflatex and flash-based pdf viewer

Slides made with beamer+pdlatex and viewed with any flash-based pdf-reader (in Slideshare, Scribd etc.) will show some clutter in the corners of the blocks (alertblock, exampleblock etc.).

If you look the slide number two here: http://www.slideshare.net/linjaaho/latex-and-slidesharefinnishfinal-7275984

There is a detour: if you use latex+dvips+ps2pdf, the problem disappears. The problem is probably related to embedding fonts in the pdf file, but I have not been able to investigate it deeper.

Finally, I'm not sure if the real bug is in Adobe Flash or in Beamer.

I found a work-around: by compiling the slides using pdflatex --output-format dvi filename.tex dvips filename.dvi ps2pdf filename.ps

There are no problems with the output viewed with flash player. This work-around is better than using latex+dvips+ps2pdf, especially if you have all your images in png/jpg format (latex requires eps images, pdflatex requires png/pjg).

Someone has been having a slightly similar problem: http://www.latex-community.org/forum/viewtopic.php?f=5&t=7427

I believe the solution is simply tweaking the commands related to forming that shadow, but I don't have enough expertise to do it. The shadow element is the thing which causes the actual problem, because if I specify: \setbeamertemplate{blocks}[rounded][shadow=false] or use a theme with sharp (not rounded) corners, there are no crappy output.
