Teamviewer v 15.15.5 Licence free version; Linux

I am using Teamviewer since a few month to teach a friend working on PC.

So far we could easily change the shared screen while clicking into the little side window. Since a few days this is not possible anymore.

What is causing this problem?

What is a possible countermeasure?

Thanks in advance for helping replies
