[-- Attachment #1 --] Hi Mario, 1. As mentioned, I am only having this issue with the Debian12 VM. I am going to test an Ubuntu-23.04 and see if there's a difference. 2. I don't have any such issue with Debian12 VM using VMware Workstation which I run on my laptop. 3. My host OS is FreeBSD 13.2-RELEASE. I CANNOT change that as it is a production server running other things. It's not a box for playing with :-) 4. Not sure what you'd me to do with #4.
