From 8bba5c81b1febeb20cdd60f1c18eb0e695cad6d6 Mon Sep 17 00:00:00 2001 From: balrog Date: Sun, 25 May 2008 00:14:34 +0000 Subject: Invalidate VNC framebuffer on every resize. On a resize, vncviewer keeps the image in the upper-left part of the screen unmodified and fills the right end of the lines with black colour. vnc.c keeps the first n bytes of the framebuffer unmodified instead - meaning that the client's image doesn't match the image in framebuffer and checking for dirty rows gives wrong results. We can either invalidate the whole buffer or implement the same transformation as the client. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@4569 c046a42c-6fe2-441c-8c8c-71466251a162 --- vnc.c | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-) diff --git a/vnc.c b/vnc.c index 4b57838..4235442 100644 --- a/vnc.c +++ b/vnc.c @@ -316,6 +316,9 @@ static void vnc_dpy_resize(DisplayState *ds, int w, int h) vs->width = ds->width; vs->height = ds->height; } + + memset(vs->dirty_row, 0xFF, sizeof(vs->dirty_row)); + memset(vs->old_data, 42, vs->ds->linesize * vs->ds->height); } /* fastest code */ @@ -1182,8 +1185,6 @@ static void set_pixel_format(VncState *vs, } vnc_dpy_resize(vs->ds, vs->ds->width, vs->ds->height); - memset(vs->dirty_row, 0xFF, sizeof(vs->dirty_row)); - memset(vs->old_data, 42, vs->ds->linesize * vs->ds->height); vga_hw_invalidate(); vga_hw_update(); @@ -1982,8 +1983,6 @@ void vnc_display_init(DisplayState *ds) vs->ds->dpy_resize = vnc_dpy_resize; vs->ds->dpy_refresh = NULL; - memset(vs->dirty_row, 0xFF, sizeof(vs->dirty_row)); - vnc_dpy_resize(vs->ds, 640, 400); } -- cgit v1.1
