Bad Frames in AE Cache

[negins75697449]

I've been having a recurring issue on multiple machines running up-to-date after effects installs. It seems bad frames are being stored in the cache. These generally don't show up during preview, but only during render. It might be a frame from the end of the sequence, but it shows up at the beginning. Or something from another sequence or project entirely. It is only detectable in the final render.

Purging the cache directly before rendering resolves the problem, at least temporarily. Though I have had the same frame show up again on the same sequence.

I assume this is related to the new preview function. It is, to not put to fine a point on it, a disaster. I have never been concerned with the integrity of an after effects render in the past. I am now generally concerned about deliveries, as a bad frame might be introduced, seemingly randomly. This is not worth any improvement in preview.

Is this a common problem? Is it on Adobe's urgent list? This has been going on randomly for months.

Please, don't make me learn Quake!

years go by and still this cache thing haunts us. What is it and why is it?! SSD physical cache? GPU cache?

RAM not purging?
