With the new Maple-2025 the GUI-fonts are tiny and more or less not readable on a 5K Monitor. The old solution using this options here:

JVM_OPTIONS="-Dsun.java2d.pmoffscreen=false -Djogamp.gluegen.UseTempJarCache=false -Dswing.plaf.metal.userFont=\"Tahoma-36\" -Dswing.plaf.metal.controlFont=\"Tahoma-36\" "

does not change the GUI fonts, as it has worked up to Maple 2024.
