Yes, this is with brltty 6.3 on Debian Bullseye. I started brltty in the 
Mate terminal like describe many times before:

brltty -b ba -x a2 -N

When the fullscreen mode is activated scroling behaviour is much better 
with brltty.

Without fullscreen mode empty lines are not always displayed and 
sometimes the content of new lines is not shown when reading a text in 
textbased apps like nano, vi or w3m. I think this might have todo with 
the way very long lines are displayed in text mode application.

Lets say you go through a text with very long lines in vi and you come 
to the end of the screen. If you go to the next line and this line is 
that long, that three lines on the screen are needed to display the 
whole content of this line, you only press one times arrow down to get 
into this new line with the computer or in the editor, but on the screen 
the content scrols three lines up to fully get displayed on the screen. 
If the fullscreen mode is used such conditions occure not that ofthen, 
because more content can be displayed.

It seems to me that brltty has problems to deal with such conditions,
buut I notice those problems only when I use brltty in the Mate 
terminal. In pure text environments such things do not occure.
