What does purple colour mean in GPU rendering profiling? In this video you can see lags in the Easter egg in Android Lollipop on Nexus 5



What does purple colour mean?
Purple is "prepare"

It has been added in Lollipop, so now we get:
draw (blue), prepare (purple), process (red), execute (yellow)

If you do adb shell dumpsys gfxinfo, the table for each app now has 4 columns (with prepare added between draw and process)

I have yet to find any documentation on this yet :)
