Body:
Package: x2goserver-4.1.0.3-10.fc34.x86_64
Version: 4.1.0.3-10

Going from a Windows 10 system running X2Go Client v4.1.2.2 Qt 4.8.6, and
connecting to a X2Go server on Fedora 34 running 4.1.0.3-10, and any time
an open application, e.g., see attached, the application leaves an overlay
or a ghosting effect and doesn't even allow to be closed. Here are some
debug logs:
