STR:
  1. Run the latest nightly on Linux.
  2. In about:config, set layers.async-pan-zoom.enabled to true.
  3. Load http://people.mozilla.org/~bballo/grid.html.
  4. Attempt to scroll with the mouse wheel.

Expected results:
  The page scrolls.

Actual results:
  The page does not scroll. Moreover, the following appears in the console output many times:

[Parent 21109] ###!!! ASSERTION: Unexpected layers id in SetTargetAPZC; dropping message...: 'Error', file /home/botond/dev/mozilla/central/layout/ipc/RenderFrameParent.cpp, line 567

This problem seems to be intermittent, as now I'm not seeing it any more...

That said, while mouse wheel scrolling is now working for me, it is much slower with APZ enabled than with APZ disabled. Filed bug 1143883 for this.

Haven't seen this since. Will reopen if I see it again.
