Sorry for late reply!
I have tried this new non-debug version and it works :)
I made some test comps with multiple instances of Fringe on top of each other and bunch of other effects. All works very fast (8, 16, 32 bit..all work, no issues so far). It is incredibile to see that kind of performance in AE. And on top of that quality of image produced by Fringe is superb.
If I will encounter any problems down the road, I will report.
Cheers
