Re: [Qgis-developer] [plugins] refreshing canvas
I understand that you don't have a use case that reproduce the problem! Can you explain better what the meaning of customized version of Dockable Mirror Map? May you file an issue for the plugin with all data displayed in help-about of qgis? Just an idea, may you also test if this append with multithread rendering disabled?
