Tuner playback do not stop when I have logged out from mate-session on Termux Android and Ubuntu 22.04 LTS (Jammy Jellyfish) AArch 64

                Dear MR Brauer,
                I Am using your excellently programmed Tuner on Ubuntu 22.04 LTS (Jammy Jellyfish)  AArch64 which is being executed by using Termux version 118 and latest stable Proot. Your app work excellently. INcluding playback, even The notification after I have closed The app when live stream play. But I Am facing one strange issue.
                When I logout from mate desktop environment and Tuner play some live stream. Mate desktop have been terminated correctly. But app still play. So I must kill it by using killall or I must terminate Xvnc server.
                I Am communicating with X11 session and Tuner by using Tigervnc and Bvnc Pro for Android.
                Why do you think, that logout routine build in to mate can not auto terminate The playback?
                Sure, I can solve this little issue by simply pressing Stop button before logging out from such non standard system.
                
                I would like to know, if logout routine build in to Mate desktop is capable to autoterminate really all processes, which hsave been exexecuted from Mate-session when VNC protocol have been used.
                
                Ubuntu 22.04 LTS (Jammy Jellyfish)  chroot container, which have been prepared by using Canonical LTD company has many advantages.
                I do not have to run dbus-run-session or dbus-launch mate-session.
                It is not necessary to execute Mate-session by this way. Because somebody advanced has preconfigured Dbus so it work even on strictly userspace based environment.
                Any little advice is welcomed.
                I Am using proot-distro scripts for Bash to install The Ubuntu 22.04 LTS (Jammy Jellyfish)  AArch 64 Bit edition.
                I have built Tuner myself with no issues at all.
                Fortnately for Me, The Ubuntu developers have compiled all needed .so libraryes so it have been possible.
