Tom, Thanks for the info. Very useful.
I haven't actually tried any of this yet, but is there still a problem where the screen flashes when toggling acceleratedRendering on/off in preOpenCard and closeCard? I was seeing this a couple months back, so I'm curious if that still exists. I haven't tried it with LC 5.5.1. It may only happen when moving from card to card using a visual effect.
