Thanks for the heads up, I didn't know that it was switching between 2D & 3D. It's not enough to annoy me, it's just something I noticed. Now that I know what it's doing and that it's functioning properly I probably won't even notice anymore.I've heard this mentioned in several reviews of the GV80. The gauges automatically default to "2D" mode if they lose track of your eyes. Then switch back to 3D when they can track your eyes again. Most likely you're noticing it switching between these modes. Some reviewers have said it was annoying enough that they just turned the 3D mode off entirely, and the 'flicker' went away.
