I'm having trouble understanding what is happening. Could you give a step-by-step description what you are doing to reproduce the problem?

Comment 2 Igor 2022-08-08 18:43:16 UTC

He really got confused. I put an Imgur image to facilitate understanding. https://i.imgur.com/XOzWwQk.png

Comment 3 Igor 2022-08-08 18:45:54 UTC

When clicked there on the wayland it creates a preview window, however, it is not closed.

Comment 4 Nicolas Fella 2022-08-08 18:55:13 UTC

So the problem is that it doesn't close when you hit Escape or click somewhere on the screen? I can confirm that
