debian upgrade cinnamon freeze software-updates

                          Some weeks ago, I updated and upgraded my Debian 11 system. My desktop environment is Cinnamon.

Now, very often, the entire desktop freezes or displays strange graphical artifacts (like lines or glitches), and the system feels extremely laggy. I have to restart to fix it.

What can I do to solve this problem?
