Title: ensure inidicators are loading dynamically to avoid mem usage Status in unity8 package in Ubuntu: Fix Released Bug description: spawning this bug based on https://bugs.launchpad.net/manhattan/+bug/1111719/comments/6 which says.... Nexus 10: Starting the shell on build #87 shows 316MB of resident memory being used before any interaction. I was unable to use valgrind to have an easier time analysing what is consuming memory so removed one piece of the UI at a time and came to the following breakdown: 1) ApplicationScreenshot x4 (92MB) used in Stage.qml 2) dash (90MB) home (33MB) music (30MB) (= 40x 0.6MB Image in AlbumTile) apps (8MB) videos (28MB) people (21MB) 3) panel (40MB) 4) greeter (32MB) 5) hud (12MB) 6) launcher (4MB) 1) ApplicationScreenshot uses the memory corresponding to its width x height x bytes-per-pixel _all_ the time, not just when it contains a screenshot. Setting width/height to 0 when application == null fixes the issue and saves the entire 92MB when no apps are running or when no transitions between apps are happening. 2) Each lens is entirely loaded and always loaded. It should be loaded dynamically instead as Michael pointed out but that would take a clean rewrite of ListViewWithHeader.qml. However the main culprit using 95% of the memory is the Images being loaded, for example in the music lens there are over 40 albums each using around 0.6MB of memory. 3) Not investigated yet but as Michael pointed out the indicators should be loaded/unloaded dynamically. 4) The greeter is already unloaded when hidden so we should be good here. 5) and 6) don't use too much memory.
