Memory Leaks errors when exiting the app when a comp uses the Particle Playground effect

Hi Karl,

Thank you so much for reporting this issue and especially for the detailed steps to show the errors. We are able to also see the errors and have opened a ticket to investigate a fix for a future version of After Effects. We will keep this post updated as a fix becomes available.

Thanks again,
- John, After Effects Engineering Team

create a composition
create a new solid and apply particle playground
set cannon particle per second to 0 and particle radius to 0
set the grid width and height to match the composition size
set the grid particle radius to something visible like 10
set a keyframe for the grid emitter to 10 particles across and 10 particles down at frame 0
at frame 1 set the particles across and down to 0
save your file
exit AE and watch the crash dialogs.
