Font display issues on Linux

[RyanTheAllmighty]

As mentioned by @jamierocks in #396 and on Discord previously, new theme font rendering looks jank AF on Linux:

After some research it looks like Linux java not using anti aliasing by default. Once you launch with certain command line arguments (listed at https://cvigano.de/blog/2018/07/15/font-antialiasing-in-java-on-linux/) it will show correctly (my Manjaro setup below showed dodgy until I added those command line arguments):

Now with those arguments it looks perfectly fine on Linux.

Issue doesn't seem to be a problem on Windows or even OSX, only on Linux.

For the moment I'm disabling the custom fonts on Linux only until this can hopefully be applied programatically in the apps startup code.

Looks like you can do it programatically. I've done that and it looks the exact same with no change

        // enable anti-aliased text
        System.setProperty("awt.useSystemAAFontSettings", "on");
        System.setProperty("swing.aatext", "true");

So options likely will be:

• Force all linux users to launch with -Dawt.useSystemAAFontSettings=on -Dswing.aatext=true arguments to get correct fonts
• Switch back to a default sansserif font only if the user is on Linux

Both options are shit, and not ideal.

Same issue seems to happen on current launcher on my Manjaro system.

So given that, going to move forward with fonts the same across all systems, and all Linux users will need to apply the flags themselves

[RyanTheAllmighty]

Ubuntu without any command line params is fine in both the latest build and the release build, so must be specific to OS/java version.

Going to close this

Going to add in an option in the settings to the launcher to use base font so users can disable custom fonts if they have issues
