Hi, Chris, sorry for the late update on this… I’ve been having a workload tsunami and these kinds of issues with Adobe CC on my MacBook Pro mean a lot of workarounds (like the one you mention here), which mean time wasted.
Anyway, to answer your question, yes, I had been applying effects right onto the clips and not on adjustment layers. As of right now, it’s the only way I can avoid the flickering. But we must agree this is a workaround and not at all practical. The reason why adjustment layers exist is to facilitate the workflow. So if Adobe leaves in a clear glitch that impedes the use of AL’s… well, that’s just terrible work.
I have written in the Adobe forums about this but Adobe doesn’t seem to be doing much about it, or at least they’re not confirming if and when they’ll be fixing this issue.
Needless to say, I still have it, and it’s one of the most annoying and frustrating things ever.
Cheers!
