ugly fonts in PhpStorm Linux version

Hello!

I use last licenced PhpStorm on Windows and I try switch to Linux. I choose Ubuntu 13.04 and Oracle Java 7. I find what fonts in PhpStorm under Linux is very ugly, without antialiasing. I try many fonts and cant find good for me. Monospaced using by default in Windows version of PhpStorm is very ugly in Linux version, Ubuntu font looks good in Ubuntu but ugly in PhpStorm. There is a solution for this problem?

Thank you!
