100% perfect workaround: https://github.com/NationalSecurityAgency/ghidra/issues/1#issuecomment-480923545

Describe the bug

On HiDPI displays on Linux, it is necessary to set GDK_SCALE= for a reasonable experience with OpenJDK apps, but setting this variable causes clipping of UI elements in every window.

To Reproduce

Acquire HiDPI machine
Set GDK_SCALE=2 or higher
Launch Ghidra

Expected behavior

Neatly scaled UI

Answer questions ryanmkurtz

I updated launch.properties to indicate that sun.java2d.xrender set to true may address HiDPI monitor issues on Linux. We've had to set that property to false in the past to get Ghidra to render correctly in VM's so I wasn't comfortable with using true as a default just yet. We might change that in the future though.

useful!
