In `support/launch.properties`, apply the following patch:

```diff
  # Setting to false resolves issue with Ubuntu when running within VM.
  # Setting to true resolves display issues on HiDPI monitors in Linux.
- VMARGS=-Dsun.java2d.xrender=true
+ VMARGS=-Dsun.java2d.xrender=false
+ VMARGS=-Dsun.java2d.uiScale=2.0
```

That's it!
