### Description

When starting a Java application - [IBM i Access Client Solutions](https://www.ibm.com/support/pages/ibm-i-access-client-solutions) - the Java window opens and displays as expected - but the application does not accept keystrokes until the window is clicked.

And sometimes the application loses contact with the keyboard and I have to exit the application. I can still exit with the Mod-Q keybinding, so the keyboard is working. I can also use other applications without any issues at the same time as the Java application won't run normally.

This is the only Java application I use, but it is central to my daily work. And I have had no issues with the Java application in the Gnome DE I used on the same Debian installation prior to installation of Dank Linux.

### Expected Behavior

Normal keyboard handling like other applications.

### Steps to Reproduce

1. Download and install the Java application.
2. Start the Java application. Note that it does not react to any keystrokes before the window is clicked.
3. Switch to another window and back to the Java window. Now it does not react to keystrokes before click.

### Error Messages/Logs

Output from `Java --version` is this:
