Fix The Font Rendering Problem On Pycharm

Almost all the java desktop apps running on PC/Mac have a common problem: font rendering. The font rendering in pycharm was so crappy that I couldn’t live with it any more. So I began to search for a way to fix it. Luckily I found a solution here

I added these lines to my ../pycharm/bin/pycharm64.vmoptions file:

-Dawt.useSystemAAFontSettings=on
-Dswing.aatext=true
-Dswing.defaultlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel

To make it even more clear, this is my complete pycharm64.vmoptions file:

-Xms128m
-Xmx750m
-XX:MaxPermSize=350m
-XX:ReservedCodeCacheSize=225m
-XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=50
-ea
-Dsun.io.useCanonCaches=false
-Djava.net.preferIPv4Stack=true
-Dawt.useSystemAAFontSettings=on
-Dswing.aatext=true
-Dswing.defaultlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel

Now the font rendering is much better now. Great! By the way, I love the default font-rendering method on ubuntu, it is much better than that on Windows.
