Hi,
I could not reproduce this issue on a clean install of bookworm so I
will lower the severity (tried on xfce/X11 and gnome/wayland).
Could you please provide the output of the following commands on the
affected system to make sure the issue is not caused by a specific JDK?
- `ls -l /usr/lib/jvm`
- `update-alternatives --list java`
I had jdk8u265-b01-jre installed in /opt that was set as default java.
Switching to java-17-openjdk fixed it. Sorry for the noise, I did not
remember installing an older jvm (likely for some other apps that needed
an older jre).
Thanks for the quick reply, closing it.
- `echo $JAVA`
- `echo $JAVA_HOME`
Best regards,
