Package: X2Go Client Version: v. 4.1.2.2 (Qt - 5.12.8) x2go blocks key presses in other windows in the Wayland display server (for example does not let any interaction with internet browsers, chrome firefox ...), until minimizing it or closing the window completely. However, it works fine in the Ubuntu display server. I am using ubuntu 20.04 with Kernel: 5.17.5-051705-generic cheers Ben
