Hello There !
Performer 2.2 is out there for quite a while now. I haven't seen any problems
like that one you describe.
Do you have any DRAW callbacks ?
Can you run your pfb file with no callbacks in perfly ? Does it still leak ?
Can you send me the smallest sample (code/model) that leaks memory ?
Thanks,
-yair
