Package: x2goclient-

Dear developers, bringing this to your attention, I experienced the
following myself:

*Title*: x2go "smearing" windows and extremely slow
*Link*: https://bbs.archlinux.org/viewtopic.php?id=268985

Client machine's OS name: Microsoft Windows 10 Pro
Client machine's OS version: 10.0.19045 N/A Build 19045
Client machine's version of X2GoClient:
Relevant settings: Session type XFCE (else using default connection,
input/output and media session preferences)
Server's OS: CentOS Stream release 8
Server's version of the x2goserver package: (@epel)
Server's version of the x2goserver-xsession package:
Server's version of the nxagent package: 3.6.x
Server's version of any other relevant packages:
xfce-polkit.x86_64  0.3-3.el8
xfce4-appfinder.x86_64 4.16.1-3.el8

xfce4-panel.x86_64 4.16.3-1.el8
xfce4-power-manager.x86_64 4.16.0-1.el8

xfce4-pulseaudio-plugin.x86_64 0.4.3-3.el8

xfce4-screensaver.x86_64 4.16.0-3.el8

xfce4-session.x86_64 4.16.0-4.el8
xfce4-settings.x86_64 4.16.5-2.el8
xfce4-terminal.x86_64 0.8.10-2.el8
xfconf.x86_64 4.16.0-1.el8

Steps to reproduce:
1. Have an updated CentOS Stream release 8 server running (e.g. a KVM) with
the latest EPEL Repo, x2goserver-xsession packages and 'Xfce' as dnf
groupinstall'ed with -y flag.
2. Have an updated Windows 10 Pro client machine running with the latest
x2goclient version, configured to ssh on port 22 to 1. with a RSA/DSA key,
auto login via SSH Agent or default SSH key on and a shared folder without
filename encoding, but automount and 'use ssh to tunnel filesystem through
firewalls' checked.
3. Start a session and experience "smearing" windows, loading and rendering
extremely slow when moving them around
4. In the session go to Applications > Settings > Window Manager Tweaks >
5. Turn off 'Enable display compositing' and close the window. Performance
and rendering rather match the preferences now.

Merry X-Mas and have a good day!

Best regards,
