[Spice-devel] [PATCH spice-gtk] Fix occasional black screen at startup

[Christophe de Dinechin]

From: Christophe de Dinechin <dinechin at redhat.com>

The problem occurs when we call spice_playback_channel_set_delay before
the channel had received any data setting c->last_time, but after
session initialization had set mm_time in the session. The result was
that the (good) value in session->mm_time would be overwritten with 0.
