I use Ubuntu 12.10 64 bit. I installed Qt4 from Ubuntu repo.
Version is Qt 4.8.3 and Qt Creator 2.5.2
I also downloaded Qt5 from qt-project.org and its version number is
Qt 5.0.1 and Qt Creator 2.6.2
When I compiled and run same project, their appearance slightly different.
What is the reason for that? Is it because of Ubuntu or Qt5?

Qt5 brought in some major changes of the GUI code, if you spot differences it's likely to be down to that rather than anything else.
