I've noticed a very lagy performance when reading specifically Texas instrument datasheets, I scroll 2 pages and bam 5s lag, then it usually works or lags occasionally. I passed the PDF through some gpt-concocted ghostscript woodoo and then they work just fine:
gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 \
-dPDFSETTINGS=/ebook -dNOPAUSE -dQUIET -dBATCH \
-sOutputFile=output.pdf input.pdf
