Berrange" The vnc_update_client() method checks the 'has_dirty' flag to see if there are dirty regions that are pending to send to the client. Regardless of this flag, if a forced update is requested, updates must be sent. For unknown reasons though, the code also tries to sent updates if audio capture is enabled. This makes no sense as audio capture state does not impact framebuffer contents, so this check is removed. Signed-off-by: Daniel P.
