with the TS5 client I have the problems of random crashes. The client just closes.
I have tried this with Pop!_OS 21.4 (Debian) and EndeavourOS (Arch). Also tried it with Gnome and Cinnamon.
If I start the Client with the console as the crash is happening I get the following lines and a coredump is written
free(): invalid next size (fast Abgebrochen (Speicherabzug geschrieben)
This problem was there at least since February, in every version I tested since then (skipped maybe 1 or 2 patches). Is there a way to start the client with more verbosity?
