Set Qt::AA_NativeWindows flag for the application
Forcing the application to use native windows by setting the Qt::AA_NativeWindows flag for the application fixes the problem.
The problem is already known by the KDE project as bug 163176 https://bugs.kde.org/show_bug.cgi?id=163176 According to upstream bug, this is still present in 4.4.1 Also according to upstream bug it might be fixed by executing konsole with the arguments "-graphicssystem raster". Since the gentoo project made raster the default paint engine this bug can be closed. While the original bug is still there it is not triggered for the average user only for those who are using the opengl paint engine. See also http://labs.trolltech.com/blogs/2009/12/16/qt-graphics-and-performance-an-overview/ Quote "Personally I would strongly recommend to use raster, it implements the full feature set, it is often faster, has the same performance profile as Qt on Windows and painting bugs are prioritized higher for raster than for the CoreGraphics backend." OK, closing it then. (In reply to comment #4) > Since the gentoo project made raster the default paint engine this bug can be > closed.
