I've seen all of those happen (the easiest way to experience them for me is to run bugaboo from low resolution and keep f10 pressed, which alternates from the debugger screen to the user screen). My guess is that both issues are related to where exactly one sets linewid and hscroll.
You could try setting all hardware scrolling registers at different positions inside your vbl routine (usually I set them as early as possible). If that doesn't change the situation, try using the hbl autovector instead of an hbl mfp interrupt (I think that this is what Paranoid is hinting in his FAQ, but I'd rather let him answer that) once per vbl to set the critical registers.
