The build was not meant for public testing, it was a copy for my update tests. When I have something for public tests, I will post it here.
I'm sorry but without a sample I am unable to look at the issue. Maybe you'll be more lucky with future 8.2 build with Nougat kernel.
I just found that 8.0.1l also has the same glitch - but it seems to happen a lot less than the 8.0.2 builds. I'm not looking for a fix - I'll wait until the nougat builds come out. I just wanted to put it out there. If the problem persists with the nougat builds, I'll provide a sample and log.
The caveat is that you can replay the same file and the stutters will occur in different places and the number of stutters will also vary - there's no consistency. As said previously, they don't seem to happen too often.
I've just reverted back to 8.0.1a - this build has yet to show a stutter - fingers crossed My previous testing showed that this build was 25p-stutter free - or at least the occurrences were a lot less frequent than 8.0.2.
PS. What are late frames?? (It's mentioned in the changelogs and just wondered if this might have an effect).
