I don’t know if someone has idea what is showing on this message. I was just working with TS5 until some update of the operating system Debian testing broke it. Perhaps can be added any parameter to the launcher. I was looking into some more information about the logs but i couldn’t fix it.
I found the issue and how to fix it in a simple way. It happened with chrome version, but I didn’t know teamspeak used it as part of itself but it does.
cp /usr/lib/chromium/libGLESv2.so /Wherever you have teamspeaksoftware
cp /usr/lib/chromium/libGLESv2.so /Wherever you have teamspeaksoftware
In my case was /opt/teamspeak-client
The thing you should only have chromium installed.
Copying both libraries and replacing what is coming with the teamspeak software it works again.
