I assume the "corruption" you mean is that the state could get out of sync between wineserver
and child process. However, is there a specific reason (for example testcase) which shows that
this is the right way to fix it? A different (and much easier) possibility would be:

-    if (ret && !hidden && (x != r.left || y != r.top))
+    if (ret && !hidden && (x != r.left || y != r.top || !old_state))
