Qt::WA_Moved being set when recreating the window.

When recreating the window in Qt4 X11, (e.g. because of setting Qt::WA_TranslucentBackground attribute on a created window), Qt tries to recover the original position of the window by moving the window with QWidget::move. However, doing that sets the Qt::WA_Moved attribute on the window which sets PPosition and USPosition in WM_NORMAL_HINTS which breaks window manager auto positioning and make all new windows that are not mapped yet appears in the top-left corder (since these window has a default position of (0, 0)).

One possible fix is to recover this attribute in qt_x11_recreateWidget before showing the window.
