Yes, it’s the same issue. I’ve already had a look at that problem. It’s not easy to solve and will need a bigger refactoring of how 3D ISOs are being played.
The problem is that currently the info about where a frame of the second eye stream can be found isn’t used. So if you skip then the stream has to be sequentially read until the correct location was found. And that takes time.
IIRC @angry.sardine has already verified that it doesn’t work on the Pi, too.
