for linux users as per request a summary of possible ways to fix font issues has been compiled in a comment below[source]:

> on linux, I finally got it working with a PERFECT font rendering (I’m on a high-dpi display), to achieve this you have to:

- Install and use Oracle JDK (I’m using 1.7) and not OpenJDK (also the patched one with fontfix was useless for me);

- Edit the file studio.vmoptions and for 64bit studio64.vmoptions by adding these lines without quotes:

    -Dawt.useSystemAAFontSettings=on
    -Dswing.aatext=true
    -Dsun.java2d.xrender=true

- Remove hinting informations from the font that you would like to use and select the new font into Android Studio preferences (Setting->Editor->Font); if you don’t know how to do this, install FontForge then:

1. Open your font in FontForge

2. Select all glyphs via Ctrl+A and clear all hints (Hints -> Clear Hints)

3. Select glyphs again and use Hints -> Clear Instruction

4. Save the font with different name ( File -> Generate Fonts)

5. Install the new font, select it in IDEA
