I'm having a problem with the Samsung Odyssey WMR headset and P3Dv4; both eyes are rendering, but it's as if the two eyes' images aren't quite pointing in the same direction. When I first put on the headset, things feel slightly off, and look slightly cross-eyed. It's not /wildly/ cross-eyed, but definitely off. After a 10-20 seconds I can get my eyes to adjust, but it's still not quite right. When I then take off the headset, I have the exact same sensation - it's as if my eyes have become slightly cross-eyed in VR and now they have to readjust to normal viewing (it's pretty disconcerting but goes away after a bit, although it tends to induce a headache).
The problem is immediately apparent before P3D even starts all the way - it happens in the FI "loading space" (the white open room shown on startup where you can recenter your HMD).
Note that this is not IPD; rather, the eyes appear to not quite point at the same point in 3D space and your brain/eyes compensate the best they can by going slightly cross-eyed.
I've found that with the WMR headset the problem does not occur in the Mixed Reality Portal. Thinking that it might be a SteamVR+WMR problem, I loaded up several SteamVR apps and none of them had the issue. As another test, I left the machine configuration exactly the same but switched to a Vive, and the problem does not occur at all.
I've tried changing my graphics driver versions as well as my P3D versions and do not see any impact. Attached is my FI log file.
