ADDITIONAL INFORMATION
Comment 1 Nate Graham 2022-01-28 19:54:49 UTC 
This is an issue in the app itself. It doesn't correctly grab the keyboard.
Comment 2 Bruno Mendes 2022-01-28 20:01:55 UTC 
Isso funciona em gnome.
Comment 3 Bruno Mendes 2022-01-28 20:02:36 UTC 
This work on gnome
Comment 4 Nate Graham 2022-01-28 20:02:47 UTC 
On X11 or Wayland?

Waylan
Comment 6 Nate Graham 2022-01-28 20:05:04 UTC 
I thought so. I believe it uses a private GNOME protocol, which is why it works there.

This is quite inappropriate. It should be using a standard one, if one is available. If one is not, one should be created, so that apps don't have to target specific desktop environments like this.

Is there anything I can do?

A few ideas spring to mind:

1. Live with it
2. Use TeamViewer in the Plasma X11 session
3. Use a different app
4. Switch to GNOME

After you said that, I did some tests:
In X11 teamviewer doesn't work with Alt Tab either, but anydesk works!! I'm new to linux and was using Wayland because I'm newer. Do I have any prejudice using X11?
Comment 10 Nate Graham 2022-01-28 20:39:48 UTC 
It's just different. Some things will be more broken compared to Wayland, some things less. In a year or two, many more things will be broken compared to Wayland, because the Wayland session is constantly improving, but the X11 session is not.
