Hello
I have problem with refreshing page after slide. It's refreshing only after tap screen.
I'm not using PDFLayoutView and i won't do this.
Is there any possibility to move page smothly ? without refreshing after next tap?
Best Regards,
Bartłomiej

Hi,
try to add
invalidate();
in your OnPDFPageChanged method.
