You do get the same error when running the same app directly (without Xnest or 
VNC) ? Then how come that the antialiasing works, when it does not have 
Render ? Either I am missing something or we do not understand each other.

But you have to recompile Qt for that. If you just unset the option in KDE and 
unset the environment variables for that (QT_XFT or something like that), 
that does not help - Qt will not use antialiasing, but will still require it. 

When you compile Qt, there is an option -xft and -xrender, which control this 
behavior and both are on by default : 


    -no-xrender ........ Do not compile XRender support.
 *  -xrender ........... Compile XRender support.
                         Requires X11/extensions/Xrender.h and libXrender.

    -no-xft ............ Do not compile Xft (anti-aliased font) support.
 *  -xft ............... Compile Xft support.
                         Requires X11/Xft/XftFreetype.h and libXft.

I guess, that on a display, which does not support XRender extension, code 
linked again a library compiled with these on will fail. I think, that 
neither VNC and XNest support it on their emulated displays.
