This always occurs for me during 60fps recording, with a majority of those being at 1080p. The most recent example occurred while playing Metal Gear Rising: Revengeance, but has also happened with various other games, all while in 60fps recording mode.
I also noticed that while recording live commentary with my Blue Yeti mic (separate audio track), the commentary audio was desynced from the video as well, meaning that the game audio and commentary audio were synced together properly. The only thing that was out of sync was the video. I confirmed this in both the Mirillis Action player and in my video editing software.

I'm not entirely sure if this info is of any validity, but could this be an issue with the recording interpreting the game's 60fps incorrectly? During my session of MGR: Revengeance, my frame rate did not stay at a consistent 60fps the full way (it's a pretty demanding game, so I did get drops every now and then). Also, cutscenes are not rendered in 60fps, meaning that the desync could become bigger if the number of frames are lower than 60, but Action treats these frames as if they are. Since my PC can run games at 30fps incredibly easily, the desync wouldn't occur when recording in 30fps mode. There would be no frame drops for Action to pick up and misinterpret.
Essentially, if the game was having drops to 30fps on occasion, Mirillis could be treating that as only half a second of footage, as opposed to 60fps being treated as a full second (since Action is capturing in 60fps mode). Is this possible? I ask because this only seems to happen to me while recording 60fps, and based on other posts in this topic, 60fps seems to be a generally consistent condition.
Like I said, I could be completely off on this, but I hope I provided enough information of my rig to help you guys out. I'm happy to see that this problem is being addressed with its own topic, so thank you, Mirillis, for doing this. I haven't had any real problems with Mirillis up until this issue. I'm sure I'm not the only one who appreciates this initiative.
