windows 11 home version 22H2

upload a pdf asset with 20 or more pages
pop pdf into a window
scroll down a few pages (3-7 pages should do it)
the pdf will scroll into blank space
resize the window, the pdf will properly draw
scroll down a few more pages
the pdf will again scroll into blank space
this doesn’t happen when not popped out into a pdf window.
OK more information. This ONLY happens when the popout window is maximized on windows. And then it ALWAYS happens. So a workaround is to not maximize the window, but… as a tablet user this is the normal process for using the popout. Open a pdf, pop it out, rotate to portrait orientation, fullscreen the window and read.
