The vendor has published 2 unique mention(s) for this bug: 1. The Mesa graphics library (specifically versions higher than 24.1.0) is causing display issues with certain system applications (such as File Manager, Settings, and Calculator) in Ubuntu 24.04 virtual desktops. Two workarounds are provided below. Workaround 1: Disable Rootless Xorg You can disable Rootless Xorg as a temporary workaround using the following commands: sudo /opt/Citrix/VDA/bin/ctxreg create -k "HKLM\System\CurrentControlSet\Control\Citrix\Xorg" -t "REG_DWORD" -v "Rootless" -d "0" --force sudo systemctl restart ctxhdx Note: Red Hat has addressed the CVE-2024-31083 security vulnerability that affects Xorg servers. Workaround 2: For continued Rootless Xorg functionality, grant the cap_ipc_owner capability To maintain Rootless Xorg functionality and ensure MIT-SHM works in ICA® sessions, apply the cap_ipc_owner capability directly to the Xorg executable, not a wrapper script, before enabling Rootless Xorg. Use the following distribution-specific commands: Ubuntu, Debian: sudo setcap 'cap_ipc_owner=+ep' /usr/lib/xorg/Xorg RHEL, Rocky: sudo setcap 'cap_ipc_owner=+ep' /usr/libexec/Xorg SUSE: sudo setcap 'cap_ipc_owner=+ep' /usr/libexec/Xorg /usr/bin/Xorg 2.
