Description
On WinXP SP3 using QGIS 1.5.0 I get two refreshes of the mapcanvas when selecting and deselecting layers.
On line 1541 of qgslegend.cpp there is a call to render the mapcanvas. However there is also a call to updateMapCanvasLayerSet() on line 1549. Should call to mMapCanvas->setRenderFlag( true ) on line 1541 be removed to stop refreshing the canvas twice?

Hi Everyone,
Can anyone give suggestions ? The bug says layer is drawn twice. But the layer is drawn twice in the mapcanvas only when the overview panel is enabled, if the overview panel is disabled then enabling a layer will draw the layer in mapcanvas only once. So is this a bug really ?

Maybe the issue has been fix in trunk? I definitely didn't have the overview panel enabled when I was doing testing with 1.5.
