[Spice-devel] [RFC spice-gtk 1/2] spice-widget: make draw-area visible on update_image

[Kevin Pouget]

When switching from a Gstreamer video stream (on the gst-area) to an
mjpeg stream, the "draw-area" was not set as visible. During the
mjpeg->gst switch, the problem does not happen, as the gstreamer
overlay is already re-created and made visible.

This patch makes the draw-area always visible on update_image. As
Gstreamer overlay is created afterwards (if it's a gstreamer stream),
we are sure that the right area will be visible.

This may not be the best place for this line...
