I think this was the issue I mentioned:
https://bugs.openjdk.org/browse/JDK-8326428

Another workaround is to set the "GDK_SCALE" environment variable, for
example:
export GDK_SCALE=2
I found the following enhancement request in our bug backlog
requesting automatic detection of the screen scale:
https://bugs.openjdk.org/browse/JDK-8238077
I changed the title to be more reflective of this and reassigned the
bug. It's something that we could consider implementing if it isn't
too difficult.

You are probably looking for glass.gtk.uiScale
I think I reported a while ago that the automatic scale detection for
KDE is not working, but apparently there wasn't an easy API
replacement available.

Hello,
When I run my JavaFX (using JFX25) application on KDE Plasma using
Wayland the fonts are incredibly small. How can I scale the
application so that things are not so tiny?
FYI: I had a similar issue with Netbeans. I know it's different
because it is Swing. I was able to get Netbeans to look good with
the following settings.
-J-Dsun.java2d.uiScale=2 -J-Dflatlaf.uiScale=0.75
Is there something similar I can do for JavaFX?
Thanks,
Chad
