Wen's patch: + const size_t width = ds_get_width(vd->ds) / 16; [...] - bitmap_set(width_mask, 0, (ds_get_width(vd->ds) / 16)); - bitmap_clear(width_mask, (ds_get_width(vd->ds) / 16), - VNC_DIRTY_WORDS * BITS_PER_LONG); + bitmap_set(width_mask, 0, width); + bitmap_clear(width_mask, width, VNC_DIRTY_WORDS * BITS_PER_LONG - width); Your patch: bitmap_clear(width_mask, (ds_get_width(vd->ds) / 16), - VNC_DIRTY_WORDS * BITS_PER_LONG); + (VNC_MAX_WIDTH - ds_get_width(vd->ds)) / 16); Since ui/vnc.h has: #define VNC_DIRTY_WORDS (VNC_MAX_WIDTH / (16 * BITS_PER_LONG)) the third parameter to bitmap_clear is the same value in both cases, isn't it? Or is this a rounding bug? -- PMM
