Package: x2goserver-4.1.0.3-10.fc34.x86_64 Version: 4.1.0.3-10 Connecting from a Windows 10 system running X2Go Client v4.1.2.2 Qt 4.8.6 to a X2Go server on Fedora 34 running 4.1.0.3-10, any time I open an application, e.g., see attached, the application leaves an overlay or a ghosting effect and doesn't even allow to be closed.
