Code review comment for lp://qastaging/~townsend/compiz/fix-minimize-unredirect-window

This is more of a strange interaction with the unity plugin's fake minimization workaround than it is a compiz issue. I think the best way to handle this would be to simply skip painting any window marked minimized - eg over here:

 /* detect occlusions */
 for (rit = pl.rbegin (); rit != pl.rend (); ++rit)
 {
     w = (*rit);
     gw = GLWindow::get (w);

...

 /* detect occlusions */
 for (rit = pl.rbegin (); rit != pl.rend (); ++rit)
 {
     w = (*rit);
     gw = GLWindow::get (w);

     if (w->destroyed ())
  continue;

     if (!w->shaded ())
     {
  /* Non-damaged windows don't have valid pixmap
   * contents and we aren't displaying them yet
   * so don't factor them into occlusion detection */
  if (!gw->priv->cWindow->damaged ())
  {
      gw->priv->clip = region;
      continue;
  }

                /* Some plugins may explicitly inhibit paint of minimized
                 * windows, just don't paint them at all if they're viewable
                 * but also minimized */
  if (!w->isViewable () ||
+ w->minimized ())
      continue;
     }
