Game looks different when compiled compared to the unity3d game view.

Unity Engine

The exe I compile for my game looks 10 time uglier than when I test the game in unity3d. Even when I put the settings
on fantastic. The standard unity slider even bugs and leaves behind a trail of the slider button. Does anyone have these problems as well and how could I fix them?

It could be something to do with the resolution or the aspect ratio.

I have solved this, apparently if you use GUI elements and do not put a Camera behind it they will look ugly in the exe but not in the game view while debugging.
