[Qgis-developer] Possible memory leak in rendering code

[Andreas Neumann]

Hi,

How comes that the same feature works fine for some but is broken for
others?

When I have it on (using a combination of Postgis, WMS and GeoTiff) I
often have redraw issues and the layer toggeling often fails. Layers are
not drawn, but appear to be on with the checkbox in the layer tree or
vice versa. I think the main problem is when also using WMS sources.

Really strange ...
