IDEA looks terrible


I recently installed IDEA 2018.1 in Ubuntu 18.04 with Java 10. It looks terrible compared to an install I have on a different machine that's running Ubuntu 17.10 and Java 9. The fonts are not aliased and it looks like a system look and feel is not being used. 

There are stacktraces of: java.lang.reflect.InvocationTargetException Caused by: java.lang.NoClassDefFoundError: com/sun/java/swing/plaf/windows/WindowsLookAndFeel

I suspect something about Java 10 is different from 9. Any thoughts on how I can fix it without reverting to 9, which does not seem to be supported by Ubuntu any longer?

IntelliJ IDEA doesn't support running on Java 9 and 10 at the moment, please use the bundled JetBrains Runtime instead, see
