memory leak on zoom in/out

doing the profiling for our app we are facing the problem that we have a memory leak (objects not collected by the GC) when using the zoomToLevel method.
You can reproduce that using your zoom example. The snapshot analysis after pressing zoom in and out shows this (see attached picture)

Hello.
Thank you for report, I opened a ticket to investigate this: https://www.assembla.com/spaces/bryntum/tickets/2386
Does this have major impact on your application?

Hi,
we can live with that for the next 2 months but need it solved to allow us releasing our product within Q1/2016

we checked again during the weekend and an part of our application (where we are showing on huge monitors permanently changing situations that need the zoom call) is running already after a day out of memory, so we need more urgent help.
thanks in advance

Could not find anything substantial here. After doing 100s of zoom in/out I see memory go up by about 1MB which could be anything (Sencha Touch internals or browser not having done all the GC yet). Could you share some more information on why you think it's a leak still?
