Looking through the painting code... Is there a good reason that we don't do partial redraws while scrolling? I mean a lot of the screen might be repaintable by just bitblt'ing the old image a bit upwards or downwards. For the usual cursor movement this is not that important because it is scrolled not so often (we might still get a speed up of two because it's scrolled halfpagewise). But scrolling by sliding the scrollbar or using the mouse wheel triggers many more redraw.
Good point, LyX 1.5 definitely needs some optimization. Are you capable of doing this, or could you at least write an entry about this in bugzilla.lyx.org? Helge Hafting
