   I tried that, but it doesn't work (if OWN_WINDOW is
   enabled). I looked at the code behind OWN_WINDOW
   and it seems that it reads multiple WM_PAINT events
   (per frame?) instead of just one and in the process
   gets also other kind of events (key,mouse) and
posts
   these messages back to system.

   In ddraw/dsurface/user.c is commented:

    /* the point of this is that many games lock the
primary surface
     * multiple times per frame; this thread will then
simply copy as
     * often as it can without keeping the main thread
waiting for
     * each unlock, thus keeping the frame rate high
*/

    So I'm just wondering if the game does exactly
this
    and without the OWN_WINDOW fix, graphics updates
get
    somehow "stacked" and GDI overflows.

    Yes the overflow entries are palette ones, but
    it also says something about "missing WM_PAINT".
