leaking pixmaps when switching activities

[tomeu]

probably need to explicitly dispose it in Activity.get_preview

[alsroot]

I guess its not core issue, tested switching between journal and ImageViewer and guppy didn't say about any leaks in shell or in activity.

What activities did you use?

Replying to alsroot:

What activities did you use?

Any activity which uses the normal screenshot funtion (eg. write is not affected, I think). The large chunk of memory is leaked on the X server, on the client side it should be very small; this means you only really see it if you run xrestop.
