Hi,

Which Qt graphicssystem do you use?  You may try to use raster instead of the 
native X11 backend.

I guess oxygen triggers primitives that are not optimized.  I know for example 
that Oxygen draws a lot of gradian which can be slow  (And Qt X11 graphics 
system does not use the latest X11 extensions to make it fast) 


But to be honest, I'm not an expert in that area.
