This shouldn't be happening. Are you running applications directly from
the Linux console or with Gnome and Orca? If you are working from the
console, are you using the screen utility, or do you have any other screen
reading software running?

I have noticed similar effects when running BRLTTY with the Yasr screen
reader, especially if screen(1) is also controlling the terminal. I
suspect the reason is that the screen itself isn't being updated properly
and this is entirely due to the combination of yasr and/or screen.


Also, can you describe exactly what happens on the display? Are there just
errors in the text as displayed, or are there ecertain dots missing, or is
it something else?
