QPixmap::handle(): Pixmap is not an X11 class pixmap
since updating to kubuntu 11.04 I am getting this message while KApplication is created, but only if I use raster or opengl as graphics system: kpat --graphicssystem raster QPixmap::handle(): Pixmap is not an X11 class pixmap this seems to happen with all KDE programs. Any idea? kdelibs 4.6.2 qt 4.7.2 -- Wolfgang

Any idea? kdelibs 4.6.2 qt 4.7.2 I remember a recent discussion in #qt-labs about this, and I think it has already been fixed in Qt 4.8 branch. The issue, if I understood the discussion correctly, is that even while you are setting a non X11 backend, it is still possible for applications to create an X11 native QPixmap via the fromX11Pixmap() function, but the checks in Qt forgot that case. Those checks were added to make sure applications don't try to access the underlying X11 pixmap so that changing the default backend to raster (or opengl) is possible for a future version of Qt. In other words, you likely don't need to worry about that warning, unless your application breaks because of it. On the other hand, I am highly interested why kpat tries to use X11 pixmaps at all.

Any idea? It's caused by your using of the raster graphics system.
