Spice agent behavior degraded under Windows 11
Description
On a Windows 11 guest, the services normally provided by the Spice agent are inconsistently available from the Spice client (which is operated locally on the host in the current configuration), with sensitivity to specific configuration that should not affect agent function.
Details
Regrettably, there is no specific test case that may be reproduced. Windows 11 was provisioned as a guest operating system targeted for interaction through a Spice client. The installation has no known problems besides the current one.
Early observations included the following:
- Clipboard sharing is one directional, with functionality for content from the client to the guest, but guest copy commands not being propagated to the client environment.
- Client cursor is not provided. The cursor is rendered by the guest.
- Changes in display resolution by guest in response to resizing of client Window normally occurred, but occasionally the guest reverts to a standard display resolution.
Log files show alarming findings.
Furthermore, earlier discussion has revealed that, against expectation, the agent had no handles to system resources during operation.
Generally, various agent functions are intermittent and sensitive to changes that should be unrelated.
