Mitigation checklist

Recommended fix / mitigation

To mitigate this issue, avoid enabling the `async-update` feature when using FreeRDP clients. This feature is not enabled by default. If `xfreerdp` is used, ensure the `/async-update` command-line option is not specified. Disabling this feature may impact performance in certain RDP sessions where asynchronous updates are beneficial.
