That's expected. Qt 4.8 uses the raster graphics engine by default, whereas Qt 
4.7 ran with the native (XRender) by default.

The raster engine is faster locally and produces better results, but is 
extremely slow over a network connection.

Try running your application with -graphicssystem native.
