Spice client needs the whole GL texture dimension to be able to show a scanout with a monitor offset (different than +0+0). Furthermore, this fixes a crash when calling surface_{width,height}() after dpy_gfx_replace_surface(con, NULL) was called in virgl_cmd_set_scanout() Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-id: 1465911849-30423-4-git-send-email-marcandre.lureau@redhat.com Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
