Resize Ghidra for High DPI screens

If you run Ghidra on a high DPI screen, you will probably find the GUI to be scaled down so small to be almost of no use.

There is a setting that you can adjust to scale the Ghidra GUI:

in $GHIDRA_ROOT/support is a file named launch.properties. In this launch.properties file is the following configuration key:

VMARGS_LINUX=-Dsun.java2d.uiScale=1

Change this line to:

VMARGS_LINUX=-Dsun.java2d.uiScale=2

Then launch ghidra and you should be good to go!

No clue what changed, but 1.5 was working for me and now I see the tons of posts saying fractional scaling doesn't work. Now I'm in the same boat, it worked originally and now it only works at 1.0 or 2.0, 1.5 no longer does anything and just gets truncated to 1 it seems.

How do I make the change on a Ubuntu system with a snap ghidra? The /snap/ filesystem is read-only.
