this seems to happen with all KDE programs.
Any idea?
kdelibs 4.6.2
qt 4.7.2
What's the widget style you are using ?
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. Adding kde-games-devel.
