qt-bugs@ issue : none
bugs.kde.org number : 83974
applied: no
author: Lubos Lunak <l.lunak@kde.org>
An ugly hack to get real transparency in Konsole working somehow, with Qt not having
any support for the ARGB visual. QApplication has one ctor that allows passing
any X connection and X visual, but that has some side effects, so this patch
adds a magic flag to turn the side effects off.
