When I try to open some PDF files, they open very slowly. All the text appear very slowly. I keep on scrolling and just the blank Page appears, it takes 3-5 minutes to load the full PDF and show the texts.
But when I open some other PDF files they open normally. But I have one PDF which opens very slowly. I tried to open this same PDF file using other applications, and they successfully opened it quickly.
Please optimise and fix this bug.
