B4J Question [SOLVED] Linux/wine - program running from the IDE uses Greek(?) font?

When running outside the IDE, all is well. However, when running the attached (based on the default project when creating a new UI one in B4J) from the IDE, it looks like a Greek font is being used for all views except the form title. Changing e.g. a button's font to Arial instead of the default one does make the button look like it's supposed to, but a Msgbox will still use the Greek font - see attached images. It happens in both Debug and Release modes. Is there a way to correct this, perhaps (wild guess) by somehow (#VirtualMachineArgs ?) instructing the JVM to use a specific font as default?

Environment:
- Linux Mint 21.1 Cinnamon
- B4J 9.80
- OpenJDK 11.0.1
- Wine: Ubuntu 6.0.3~repack-1

Thanks in advance!
