Yeah, I’ve tried a couple of different times to capture the full page without much luck. The only technique I have seen publicly is to disable scroll notifications, hide absolute-positioned elements and scroll the page one viewport at a time (a hack I’m not excited about). I’m happy to implement it is someone has ideas for how (though doing it as part of video capture may be too heavy).
That was my inclination as well. It sounds like a good challenge, though. When I get some time I’ll see if I can get a prototype working in a private instance - will let you know if I make any progress.
