+SVN commit 1089160 by ggarand:
+
+automatically merged revision 1089159:
+Critical performance fix:
+
+There is a huge difference of behaviour between DEBUG and RELEASE
+builds of Qt 4.6, that breaks scrolling in KHTML.
+
+Using QWidget::scroll() on a widget that doesn't have WA_OpaquePaintEvent
+attribute set works just fine in Debug, but completely breaks down in
+Release, causing the whole view to get repainted always.
