Hi, Thanks Jukka, seems like a regression. It happened between 3673 and 3732. @Ede, I could not investigate too much, because I'm no more connected to the web at home, but I noticed one commit with many changes about Layer, LayerManager and a new interface Disposable (revision 3724). I think the regression could be related to this commit,
