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.

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
