hi winehq!

When I was debugging an application, I noticed that you had added patch for new_surface:

85f81948de1d7fe6d6d16f681a3a7cf8c08a566f, 6ccb94392a8ef4bca701ae2a560f4ea1da677edd

They cause bugs with the following window refresh:

1. Dragging the window edge to scale the window will cause a window top toolbar refresh error.

2. Changing the window size also causes a window top toolbar refresh error.

3. Open the image with the app. The first image will be incomplete.

4. Window showing a transparent background whose background has not been drawn.

After trying to modify the conditions of new_surface, I was able to fix most of the bugs, but not the root of the problem.

At the moment I can only revert these issues by removing the relevant patches.

user32/winpos.c/set_window_pos

if (!EqualRect( window_rect, &visible_rect ) || new_surface || valid_rects)
{
    if (new_surface && swp_flags & SWP_FRAMECHANGED)
    {
        extra_rects[1] = new_surface->rect;
        OffsetRect( &extra_rects[1], visible_rect.left, visible_rect.top );
    }
    if (valid_rects) extra_rects[2] = valid_rects[0];
    else SetRectEmpty( &extra_rects[2] );
    wine_server_add_data( req, extra_rects, sizeof(extra_rects) );
}
