[poppler] Splash rendering problems

[Тодор Африкански]

Hello,

I have some rendering problems with the splash engine and I need some help.
I'm writing this application able to display PDF files and I use poppler. I
am using the D language, so I have wrapped most native poppler C++ classes
in C functions and put them in a MSVS DLL. Everything works fine, besides
this. Some elements on some pages in certain files appear completely masked
with random color, sometimes even gradients. For example the text. The text
on some pages appear completely filled with random color. Or sometimes the
text is fine but the images are just color rectangles. Or some part of the
text is fine and the rest is not. It is very strange. I am looking for
advice where to look for the problem as I have no idea what could be causing
this. This behavior is specific for each PDF file. Only that everytime I
reopen the application with the same file the mask color is different.

I'm attaching a screenshot showing the problem. Additionally here is a copy
of the image: http://paintballforce.com/_tmp/Clipboard01.png . Almost all
pages in this example are displayed corretly, but few of them look like on
the screenshot. Notice that it is not the whole page that is misrendered.
I've tried the problematic documents with old version of SumatraPDF that
still has poppler engine in it and they look fine. So the problem is not
that these pdfs are not supported by poppler.

Thank you,
Toshko
