I have lyrics on the iPad, and prefer to scroll manually as the song is going forward.
I don't change a whole page at a time, but scroll e.g. from a verse to the chorus.
So I made my pdf files with very large page heights. Some of them 50 centimeter or more, since I don't really need page separations.
When I scroll a little fast on these large pages, I get black bars on the top and bottom of the screen, until I stop the scrolling. It looks like the GPU of the iPad is not strong enough to handle this.
It's a quite new iPad Pro, so it should be powerful enough.
Is this normal behavior, or can I adjust some settings to prevent it?
It's not a big deal. Just a little annoying!
