The framebuffer_update_display() function returns the dirty scanlines that were touched since the last display update, however artist_update_display() always calls dpy_gfx_update() with start and end scanlines of 0 and s->height causing the entire display surface to be rendered on every update. Update artist_update_display() so that dpy_gfx_update() only renders the dirty scanlines on the display surface, bypassing the display surface rendering completely if framebuffer_update_display() indicates no changes occurred. This noticeably improves boot performance when the framebuffer is enabled on my rather modest laptop here, including making the GTK UI usable.
