Bug in the QT or problem of configuration?

When using Lazarus in linux, I have used widget Qt, for two reasons:

1.For the appearance of the programs
2.For the available documentation and easiness to implement routines of the Qt directly

But as everything they are not flowers, always a problem appears.

In this in case that, I do not know if bug of the Qt is one, or if it is problem of configuration in linux.

Go to the problem.


In the internet speed of 500kbps, the programs with widget Qt load normally, but in the speed of 2kbps, delays an eternity to load, as if in some way the Internet it was intervening the shipment of the program.

Somebody already passed therefore?

Is one bug in Qt library or problem of configuration in linux?

Any help will be coming well.

Thanks.
