Thank you for the patch. Before I can apply it to pdfsizeopt, I'll make sure 
it's the
right thing to do.

Could you please send me a small example input and output PDF and also specify 
the
version of Acrobat Reader and the operating system you use?

I produce a better dirty patch ;-)

I have created a small PDF to illustrate the problem.

Tested on Acrobat Reader 7 8 9 same visual BUG

The latest pdfsizeopt has a --do-unify-pages= flag. The default, 
--do-unify-pages=true may not work for you. Could you please attach a sample 
.pdf whose optimized version Acrobat Reader can display properly with 
--do-unify-pages=true, but not with --do-unify-pages=false? Please also specify 
the Acrobat Reader version. Please use the latest pdfsizeopt.

Unfortunately, I couldn't reproduce the problem with the integral.merge.pdf 
previously attached. I get very different output for it:

I close this issue now. I'll reopen it once I have the file which which exposes 
the problem.
