Thank you for the update, however this is a good and bad news at the same time. The beta release of Scene Graph seems to be around the corner and this issue is very frustrating. I have applied a workaround everywhere I need it, but for a released experience this will likely create hiccups of different sorts. For example in my case I will have to swap / programmatically re-initialize materials on hundreds of mesh components. I’m not sure if this could also affect PSO pre-caching in some sort (not an expert on that bit). However I suspect that I’ll run into some frame drops, temporary or repeating (I already one frame drop on mobile device that I can 100% reproduce when I update the material parameter of a re-initialized material).
