I was testing out the demo, and i was experiencing very odd behavior with the handles. In some instances moving one handle would cause the others to move appropriately, and other times they wouldn't, but then when you went to click on another handle they would "snap" to where they were supposed to be. Moving a handle also seems to cause the other handles to jitter in place as you move them. After about 30 seconds of playing with the demo chrome complained about memory allocation issues with webgl and locked up. The player is taking 700 megs of memory (the player not chrome itself, i used chromes task manager to check it). So there is still some memory issues it seems? I posted a screenshot of the issue to the slack Bug Reports thread.
