Warning when disabling and enabling video

The warning is not important. Somebody is setting input acceptance for the same surface twice. It should not cause any problems.

Best regards

Subject: Warning when disabling and enabling video


We have queries regarding GENIVI IVI layer/surface management. Could you help?

We are getting a warning when enabling and disabling video many times.
The warning message/log is from the wayland side.

invalid id_surface in controller_listener_surface
Warning: input acceptance event trying to add seat default, that is already in surface 1000

We are only the user of Wayland Client API.
We are not able to debug further.
We have adjusted the Wayland API order as following.
We don't see any further problem from a wayland client API user's point of view.

1. enable the video device


2. disable the video device


We would like to know the real root cause of it on wayland side.
Could you advise us what we are doing wrong on our side.
Is the above sequence correct or should there be any change?
