Bug Description
Opening lots of apps has a quite big bad impact on the overall rendering performance of the phone. Starting with around 4 apps, first slowness is noticeable, increasing the number makes it become worse and worse. At the number of around 10 apps the phone is mostly unusable (bug 1267323)
Note, this is not some app hogging the CPU or anything, given that all the apps are suspended and CPU usage is at 0%. It seems like each app would add a major overhead to the rendering code in the display server.
Its nicely visible with the Launcher: With no apps the Launcher folding animation is smooth and nice. After opening the apps it gets quite bad.
Given that the right edge animation looks best with many apps in it, this is becoming a blocking issue for the work on the right edge animation.

I can confirm this, and it looks like a rendering issue, since both CPU is idle and RAM is free.
