When assigning a layer to each icon on the vertical homescreen the FPS is near 60 but has many frames taking 20-30ms giving a poor frame uniformity and jerky scrolling.

If this has anything to do with too many GL calls, I just landed a patch on inbound that reduces the draw sequence to about 1 uniform set and 1 draw call per layer for a sequence of similar layer draws. Can you remeasure with that? I am working on a patch to draw multiple layers with a single draw command as we speak.

It doesn't. We have 20 draw call on the Flame that can perform 200 draw calls at 60 FPS. I have more information which I will write shortly.

I guess I moved on working on bug 1015984. Some of the issues are shared on that bug (and some are specific to image layers). Lets revisit this once that bug is solved.
