How many rows in the list? (i.c.w. useVirtualLayout) The setup you mention shouldn't be a problem I think (unless the image you talk about is 200MB a pop), but depends on the implementation (details). E.g., if the buttons are created every scroll, instead of reused, that might be a cause.
Any code you can share, can help (me at least) to track down the culprit. Not a guru here though, so maybe others will know off the top of their heads :) Ben P.S. We are talking desktop app here right? Mobile is a different beast all together (for me). On 3 sep. 2013, at 15:16, Federico De Maddalena <f.demaddal...@patente.it> wrote: > Hi!
