[winswitch] Warning: delayed region timeout

[Antoine Martin]

Hi,

ACK packets are sent as soon as the picture has been decoded and/or
painted on screen. In both the python and the html5 clients, that's done
using the send_damage_sequence function.

If you have more queries, please try creating a ticket on the bug
tracker. Make sure to always quote the full error message, ie not:
"I get error"

Cheers,
Antoine
