Linux question

[Malte Brill]

Hi,

can anyone make sense out of this?

/usr/lib/gtk-2.0/2.10.0/engines/libqtcurve.so: wrong ELF class:  
ELFCLASS6

This pops up in the shell after starting a standalone we built. Also  
under KDE the whole system seems a bit unresponsive. While being quite  
snappy under Mac OS and Windows, Linux does not seem to like stacks  
wich make use of blending. Any advise on which things should be  
avoided when deploying for Linux?

Cheers,

Malte
