@Apasas - At first I thought it was a misalignment of images (happens sometimes in VR), then I closed one eye at a time and the left eye image is blurry or out of focus. I disabled stereoscopy on my player to make sure it wasn't my eyes then both eyes were blurry. Most players use left eye image when stereoscopy is disabled (monoscopic).
The effect is like I'm having a sudden problem with my left eye vision.
It is from start to finish, so the one-minute preview has the same problem.
