some pdf can not be rendered normally

some pdfs can not be rendered normally , pics can not be rendered.
Please check the pic attachment below.

I've try
render_mode = 0
render_mode = 1
render_mode = 2
and none of them is avaliable to solve the problem

Today a new beta will be released, it should fix your issue.
In the meanwhile, may you open a support ticket here www.radaeepdf.com/support and send us that pdf file, I'll check it in advance for you.
