“Arrrgh!” cried the perfectionist Ubuntu user when looking at his screen, “My window borders look awful!” 

If you are using Ubuntu’s default Ambiance theme then you, like the exaggerated exmaple user above, have jagged window corners bordering your application windows.

Now, it’s not the biggest, most-kernel-panicking deal for most users (enter your pithy retort of ‘I never noticed” at this point) but for others it… Well, it damn well irks.

When you look at the window corners you can see that they are not perfectly rounded. Instead they appear ‘step’ like.

The good news for everyone is that a fix is planned in Ubuntu 12.10. But in the meantime there is a way to get anti-aliased corners in 12.04 – though you will need to be a paid member of the angularity fan club.

Welcome Ambiance squared.


Ambiance Squared is an option download; you don’t need to install it if you don’t like it.

Getting it is as easy as adding our PPA:

  • sudo add-apt-repository ppa:kokoto-java/omgubuntu-stuff
  • sudo apt-get update && sudo apt-get install square-ambiance-theme

Once installed you can apply the theme using a tool of your choice. We recommend MyUnity which can be found in the Ubuntu Software Center.

Once applied, you’ll be left with angular window borders free from aliased stepping:
