[GD-Windows] Windows paints my window!

[Javier A. <ja...@py...>]

Hi!

During long load times (not so long actually, but hey) Windows sometimes
seems to decide that the game's window needs repainting and erasing. The app
is not responding to messages because it's busy loading stuff. I thought
that setting the hbrBackground of the WNDCLASS struct  to NULL was enough to
prevent this, but it still paints the window white. This only happens when
the game runs in fullscreen mode, never in the windowed mode we use for
development. Even funnier is that it only started happening a few days ago,
but we have been unable to find any changes we might have done to the Window
or DirectX handling code for the past _months_.

Any ideas where to look at? Even the slightest trace of a pointer will be
greatly appreciated.

Thanks,

Hi,
Are you returning TRUE to the WM_ERASEBKGND message?

This is in our windowproc:

case WM_PAINT:
  {
    PAINTSTRUCT paint;
    BeginPaint((HWND)hWnd, &paint);
    EndPaint((HWND)hWnd, &paint);
    return 0L;
  }

case WM_ERASEBKGND:
  return 1L;

And this is our window class setup:

 wcex.cbSize = sizeof(WNDCLASSEX);
 wcex.style   = CS_HREDRAW | CS_VREDRAW | CS_DBLCLKS;
 wcex.lpfnWndProc = (WNDPROC)WindowProc;
 wcex.cbClsExtra  = 0;
 wcex.cbWndExtra  = 0;
 wcex.hInstance  = (HINSTANCE)m_hInstance;
 wcex.hIcon    = LoadIcon((HINSTANCE)m_hInstance, "PRAETORIANS");
 wcex.hCursor   = LoadCursor(NULL, IDC_ARROW);
 wcex.hbrBackground = NULL;
 wcex.lpszMenuName = NULL;
 wcex.lpszClassName = "Ventana";
 wcex.hIconSm  = LoadIcon(wcex.hInstance, "SMALL.ICO");
 RegisterClassEx(&wcex);
