Flashing screen while playing FBNeo on Retroarch

[Xalechim]

Hi all,

I'm experiencing a weird glitch with all FBNeo arcade games when playing them with the FBNeo core on Retroarch. I don't think this is a launchbox issue, but hoping someone here has some ideas. See the attached video for the flash frames of what looks like the romcheck screen for the game. It happens no matter which FBNeo game I play.

I also encountered this issue and came here while searching for a solution.

I'm experiencing the exact same symptoms. When I use Launchbox to run RetroArch with the FBneo core, it exhibits the same symptoms as in the video. The screen repeatedly flickers, showing and disappearing text strings.
