Hi!
With openjdk, I get very ugly chat text. Some thinner text is barely readable (like the one on the "friends options button").
Did someone already take a look at this, try to fix it? Not sure where that font is coming from and how it's rendered... Is SK using swing for this? Tried overriding the font hinting for the java vm, but that didn't seem to change anything.
Which JRE are you running it with? JDK is just a bunch of development tools.
