Making Ghidra scale on HiDPI screens.
Tested on Kali Linux 5.18.0-kali5-amd64, Ghidra 10.1.4, Java 11.0.16.
Ghidra doesn't scale to HiDPI screens, but this can be fixed by modifying the launch.properties file. This is located in <GhidraInstallDir>/support/launch.properties, which when installed using apt is /usr/share/ghidra/support/launch.properties.
Change this setting:
VMARGS_LINUX=-Dsun.java2d.uiScale=1
VMARGS_LINUX=-Dsun.java2d.uiScale=2
