** Description changed:

  When moving a window, the screen doesn't update except for the mouse
  cursor if I move the cursor more than ~20 pixels per second, until I
  slow/stop.  If I continue to move the window back and forth
  continuously, the screen will never update.
  
  Occasionally a new window will have fluid movement, but that goes away
  under many different circumstances (alt-tabbing to it, having it touch
  an edge of the screen while moving it, etc), at which point it acquires
  the taint, and will never move smoothly again (i.e., after a
  minimize/restore).
  
  This occurs with or without sync-on-vblank.
  
  This still occurs after updating from the latest in -proposed and
  rebooting; it seemed like some of the recently fixed bugs regarding
  lazy-positioning in the move plugin might have also fixed this, but
  evidently not.
  
  Before updating to -proposed, I compiled a version of the move plugin
  with an instrumented moveHandleMotionEvent which logged which branch was
  being invoked of:
  
- 	    if (ms->optionGetLazyPositioning () &&
- 		ms->hasCompositing &&
- 		!MoveWindow::get (ms->w)->mLocked)
- 	    {
- 		/* FIXME: This form of lazy positioning is broken and should
- 		   be replaced asap. Current code exists just to avoid a
- 		   major performance regression in the 0.5.2 release. */
- 		w->serverGeometry ().setX (w->geometry ().x ());
- 		w->serverGeometry ().setY (w->geometry ().y ());
- 	    }
- 	    else
- 	    {
- 		w->syncPosition ();
- 	    }
+      if (ms->optionGetLazyPositioning () &&
+        ms->hasCompositing &&
+        !MoveWindow::get (ms->w)->mLocked)
+      {
+        /* FIXME: This form of lazy positioning is broken and should
+           be replaced asap. Current code exists just to avoid a
+           major performance regression in the 0.5.2 release. */
+        w->serverGeometry ().setX (w->geometry ().x ());
+        w->serverGeometry ().setY (w->geometry ().y ());
+      }
+      else
+      {
+        w->syncPosition ();
+      }
  
  Windows used the first branch when moving smoothly, but _only_ the
  second branch once they had been "tainted".  I haven't repeated the test
  with the code in -proposed, although I believe this was reworked
  somewhat there.
