lyr = iface.activeLayer()<br>

If I turn off caching in Settings, I don't have a problem with my plugin.<br></blockquote><div><br></div><div>Which version of QGIS is that?</div><div><br></div><div>In QGIS < 2.4 you had to explicitly call lyr.clearCacheImage() if the caching was turned on - otherwise the renderer would still use the cached image stored in the layer's instance.
