lemmy,
it would be entirely possible to make a system do autoscrolling right now.
however it would drive you crazy because the screen suffers from horrendous tearing artifacts when using the normal x11 pathways. I started liqbase by using the "normal" methods of updating but was really unhappy with how it looked with text.

I get round it by a combination of crazy coding and the choice of display mode I use.

liqbase lives in the XV video mode using YUV colors, normally used by media players to render movie frames and not used by any GUI software.

I have built the software stack from the ground up to operate as efficiently as possible at the expense of compatability.
Its not childsplay to expect the entire stack to be converted from its native RGB mode to the YUV mode and carry on as if nothing happened and would suck even more cpu trying.
Its something I have had to come to terms with but am happy right now because it gives excellent performance, not just here but on other devices I try it on ( and for different reasons - on faster machines liqbase simply requires less cpu and hence does not drain the battery as quick )
