In all honesty though, even if fixing this kind of bug would create a new one, its not a bug that should be ignored. Its a major one imo (fix this bug and create a new one, I would personally take my chances). I remember after effects had a bug in a recent update, were audio always was set to low quality when you export, which was very annoying, and it wasn't fixed for months! This bug is worse, and happily I read this thread before updating so Im staying away for now, I hope it won't take months to fix this one.
It makes sense and Im really happy to hear a chunk of the AE team is working on optimizing the code.Though I think they should devote more people to that. AE is such an old program that I assume those working with keying or other of the features that have been updated lately, they bought a better plugin for it allready. I would much rather have NO updates for a year if that means the program would become more stable, faster and in the future they would not need to patch up layers and layers of old code, as you say....and from what I remember the response from the community was pretty much the same from every single one when it was asked in public what people wanted in the future updates....a faster program. THe content of AE is all ready great, and you can get plugins for pretty much everything you need...except optimization and an up to date software that uses the computer to the maximum potential.
