I've tried to add the canvas.repaint() with my canvas.refresh(), and it
seems to work !
Thanks !

Thanks for your answer.
Actually, I wonder if my refresh problem is not only on QGIS 2.2.
I believe I had not reproduce this behaviour on QGIS 2.4 and 2.6.
And I didn't know about the bug.
I have these two points to analyse.
The multithread rendering was available in QGIS 2.2 ??
I'm going to work on the two previous points.
Thanks again,
Alexia

Hi all,
I have a plugin using a customized version of Dockable Mirror Map.
I use it to display each processing result in a new view.
I get a strange behaviour with my plugin :
Some times, the canvas stays white. A scroll in it is fine to reload it and
my image is displayed.
I get this problem since the beginning of the development on QIGS 2.2. It is
for me a "random" problem, because I can't say why I get these white canvas.
But, when I get it I save the projet with the white view, and when reloaded,
the canvas is still white.
I've played with canvas.refresh(), canvas renderer flags and even with
canvas.freeze().
I can't understand the behaviour I get, maybe I have a wrong usage of the
properties above.
I also thought about triggerRepaint()...
Thanks by advance,
Alexia
