Bug Description

Using emulator with the following build:

current build number: 244
device name: generic
channel: ubuntu-touch/devel-proposed
alias: ubuntu-touch/trusty-proposed
last update: 2014-03-18 14:56:03
version version: 244
version ubuntu: 20140318.1
version device: 20140304

It seems Unity8 leaks memory when rendering anything into the screen. If you boot and let the welcome screen running, you can easily follow the leak with a top, until OOM kicks in and kill unity8.

Indeed, wonder what's special about the emulator here...

A simple qmlscene leaks, too (obviously slower), see for example:

Rectangle {
  gradient: Gradient {
      GradientStop {
          position: 0.0
          SequentialAnimation on color {
              loops: Animation.Infinite
              ColorAnimation { from: "DeepSkyBlue"; to: "#0E1533"; duration: 5000 }
              ColorAnimation { from: "#0E1533"; to: "DeepSkyBlue"; duration: 5000 }
          }
      }
      GradientStop {
          position: 1.0
          SequentialAnimation on color {
              loops: Animation.Infinite
              ColorAnimation { from: "SkyBlue"; to: "#437284"; duration: 5000 }
              ColorAnimation { from: "#437284"; to: "SkyBlue"; duration: 5000 }
          }
      }
  }
}

Not sure where to assign this bug... since it's obviously not unity8-specific, maybe we should check if it still happens with 5.3?

This has most likely been fixed a while ago when we fixed that leak in "everything". Riccardo, can you confirm this is still the case?
