I've landed new diagnostic asserts but the latest crash report from Chris has shed some new potential light on the problem:
From the critical log I can see:
> [G274][GFX1-]: SSP:Add 176093660498 init (t=218368)
> [G275][GFX1-]: DataSourceSurface of SharedSurfaces does not exist for extId:176093660498 (t=218368)
If we fail to map the surface into the compositor process memory space, that would indeed cause the problem we see.....the other crash reports don't have that print but the buffer seems to be completely filled often so it might have gotten truncated (at least the ones I've looked at).
