Just noting the same thing happened to me starting last night. I've run through the troubleshooting steps outlined above as well as updated to the latest OS available to me (78.1027). I've been advised from meta store support to try and factory reset but I haven't taken that step just yet.
In answer to the questions you asked
- Do you see the double vision only on the edges of the screens, in the center or all over?
- Does this occur when standing still, when moving or all the time?
- Both standing still or moving. When standing still I can focus on augmented reality (UI elements like the app store or menus) or I can focus on real objects in the pass through. But not both. It's as if the augments are being placed very differently for each eye. Moving forward and backward the effect is even more interesting. Virtual objects scale 'faster' then real objects do e.g. moving 1 ft forward in the real world moves virtual objects 2 ft closer to me
- Can you attempt to send a screenshot or failing that, a photograph of the screen itself?
- I took the video but the effect isn't visible in the 2d video. In fact the effect isn't visible if I close one eye or the other. Only if both eyes are open is it clear that virtual object depth has become disconnected from real world depth.
