--- Comment #1 from Filzmaier Josef <j.filzmaier at gmx.at> ---
I can reproduce this issue on my lenovo thinkpad x1 carbon gen9.

I do have a 4k screen and scrolling pages within this document is almost
unusably slow.
Opening the PDF in Firefox (wayland enabled) has way better performance.

This Problem is *not* dependent on a secondary screen being plugged in (at
least in my case)
